Video Transcript for etrailer Electric Jack with Footplate Review

Speaker 1: Today we're going to be taking a look at the Etrailer Electric Jack with Footplate designed for use on A-frame trailers. This offers 25 and 1/8 of an inch of lift and a 3500 pound capacity. In black, the part number is EJ-3520-BBX and in white, it's part number EJ-3520-WBX.Now an electric A-frame jack like this is going to take a lot of the work out of hooking it up and disconnecting your trailer. With these big enclosed trailers, campers and even utility trailers, it can be quite heavy. Getting a manual jack, the operator lifting it up to your ball, it's just not very feasible.With this, we're able to very quickly and easily adjust the height up and down. When connected to either our vehicle or to a 12 volt power source inside our trailer.

Now on the front of the jack, you're going to have two buttons to operate it. One will be for up and down. The other's going to be for the light. Now this can be pretty handy. We've got a lens here on the bottom that shines right down on our coupler, and also out towards our vehicle so we can make our wiring connections pretty easy.Now the cover on the jack's designed to shield it from any kind of moisture or anything like that.

As the rain comes down, it hits, it's going to run off, we've got our seam around the bottom side here so we shouldn't have to worry about that moisture getting in. Also you've got a cap here, you're gonna turn it and lift up. It allows you to access the emergency override. Now in the event that you don't have a power supply or maybe your trailer's battery is going dead, we can take the provided handle, place it down and on and easily raise or lower our trailer so we can still make our connection.Now as you can see, the jack's designed to really give you a lot of lift on the front side of your trailer. So this can help with run-off and drainage on the backs so things don't sit on top.

And something else you'll like, when it gets to it's fully extended position, it just stops, we don't have to worry about overdoing it.With it in this position, we'll get a bracket height measurement that'll be right up to that mounting surface. It's going to be about 33 and 3/4 of an inch. So if we retract our footplate, that'd be closer to that 28 and 1/2 inch mark.We see fully retracted with that leg extended. We're at about 14 and 1/2, 14 and 5/8, so if we subtract the drop leg, it puts us at about 9. Now the outer tube of our jack and the plate are going to have a black powder coat finish.

While the inner tube or pinning clip and drop leg are going to have the zinc finish. Both of those are going to be great at resisting corrosion.Now not only does this drop leg help to save us some wear and tear on our jack and also us some time, but it also helps to spread the energy or the force of that jack out over a greater area. This can be really important when we're on softer surfaces and prevent it from sinking into the ground.Now another measurement to keep in mind will be from the top of our bracket here to the very top of our jack, we've got about 20 and 1/2 to 20 and 5/8 of an inch. You just want to make sure if you have anything overhanging, you've got enough room for that to fit in.Now to begin your jack installation of course, you'll want to remove your old jack. Save the hardware with that though. The jack doesn't come with it, so you'll want to have that handy. Then we'll just remove our footplate here, set to the side and we'll be ready to drop our tube down through. Now this is a two and a quarter inch outside diameter tube. So you just want to ensure that your holes large enough to accommodate that, and you should have your triangle shape bolt pad in there. It's pretty standard on A-frame trailers. It's going to bring that right down through and line those up.Now if you don't have hardware already existing or if you need to replace it if yours is damaged, you just want to ensure that you're using a 3/8 inch diameter bolt that needs to be at least a grade five. As long as you meet those requirements, you'll be in good shape. You see ours had a lock washer on it. I'm gonna keep that and then we're gonna place on our flat washer. The flat washer's provided with the jack as well as the star washer. That's gonna go underneath that flat washer. When we tighten it down, it's gonna penetrate that paint, so we get a good ground. We're going to do that in all three of our locations. Now we're going to torque our fasteners down to the specifications listed in the instructions.Now once we've got our jack nice and secure, we now are going to move onto wiring it up. You'll see they give you a good length of wire here. What I like to do is run this along with my seven pole. You can there are a couple zip ties already on there. It really uses many zip ties as you need to keep everything nice and secure.Now you can get power for this from two ways. If you're using it on a camper or an enclosed trailer, something that already has a battery on board, you can just run this to your battery. It's going to be grounded here so everything should work as long as your battery is grounded. If not, if you don't have an on-board battery, you can do it right off the power coming through your vehicle through your seven pole plug. Ours runs to a junction box. The wire coming out of the junction box is here and that'll provide the power that we need when we're hooked up. So, if you have the option to hook it up to the battery, I recommend doing that, then you'll always have power. If you don't have a battery on-board, you'll only have power to the jack when this is plugged into a truck with a working 12 volt power outlet or any vehicle for that matter with a working 12 volt power plug coming out of it.Now the extra wire, I've just coiled up here at the base of the jack, really keeps it out of the way, not really too much of an issue, and then you'll have extra if you ever need to change it or make any modifications. We're going to run that to our power wire here. So let's cut them off to the appropriate length. We're going to get both sides of that stripped back and we're going to use a butt connector to connect 'em, this is part number DW05745. It's a heat shrink butt connector. Since this is going to be out in the elements, it's a good idea to use the heat shrink just to protect it from the moisture. Got both sides of that crimped down, and then we'll use a heat gun, a mini-torch or a lighter and get that shrank. Just going to apply a little heat at a time here and you'll see that start to shrink down around the wire. Once you have it fully shrank, almost looks like your wire magnifies a little bit.Now we'll just use a couple more zip ties. Make sure our wires are nice and tight so they don't get hung on anything. You see on our drop leg here, we've got four holes to choose from. This one will have it in it's highest position. That's going to be more of a stored position. But this gives us four holes with an inch and 7/8 between 'em for a total of 5 and 5/8 inches of adjustment. That's just going to save wear and tear on our jack and the time we have to have it operating. We can get that down and then use our jack a little bit more quickly.Now we'll take the provided pin and clip. You just want to set your drop leg where you like it, bring that through and then secure it with the clip there. And as you can see, that's drastically going to reduce the distance our jack has to travel. Now we'll hook it up to our vehicle as you can see here so we have power, run the jack on down and support it.That's going to complete our look at the Etrailer Electric Jack with Footplate.

Ok.... the customer service from ETRAILER totally saved the review! These guys are incredibly awesome. I ordered 2 of the jacks. The first came with a broken housing cover , the light had beed disloged, and the up down switch was wired backwards. (Up would put the jack down and down would put the jack up) Solution? Glad you asked! I contacted ram about the cover.... waiting! The light was easy to correct, just had to slide it back into the slit that holds it. Switch, well.... if-your2 not comfortable with wiring, I recommend not even attempt to rewire. I just popped it out of the cover, twisted 1/2 turn, popped it back in. Total time to correct.... 8-10 minutes. Total time to install, 15 minutes. Total job less than 30 minutes. Would I recommend this jack... YES. Despite a shipping issue to crack the housing ... its easy to install, price right, powerful. I dont have to hand crank. Simple correction to the switch. And they could use some r&d improvment on the light... but excellent jack! It does what i meeded it to at an affordable price! 494266

This was my first time shopping at ETRAILER and I was hesitant because of their low prices and sceptical of the quality of their products and the service I would receive. But after giving them the benefit of the doubt I am a believer. They excelled at both quality and service and I received my order in just a few days. The quality of the electric jack exceeded my expectations and I am very pleased. I will definitely be shopping etrailer in the future. 365043

Everything is good except, the LED light bracket has seemed to slip down inside the lens housing I guess I can live with that I would take the lens cover off but it seems to be glued. It would have been five stars 404315

The jack works well. Unfortunately with it mounted in the forward position it doesn't have enough clearance to open the tailgate on my truck. I tried to mount it so the motor is projecting out one side. Unfortunately because the mounting plate is a triangle with mounting holes in only 3 positions you can't rotate it 90 degrees You have to rotate it in 120 degree increments. When I do this the motor angles back enough to hit the propane tanks. I was aware of the possibility of tailgate clearance when I bought it. I wasn't worried as one of the expert answers said you can rotate it to any position you need. Unfortunately that's not true as you only have 3 options, Not exactly "any position" . I wish i had bought one of the similar (better) priced well rated jacks on another online retailer. They have a round plate and curved slots for the bolts. With that I could mount it turned 90 degrees to one side. 521671


Comments

Unfortunately, unless the jack has laterally slotted mounting holes, just about any tongue mounted jack will only be able to rotate in 120 degree increments.

Was standing next to my RV looking at the hole in the tongue where the jack goes and the UPS driver stops in front of the house. He has my new electric jack I ordered the day before and hands it to me. 10 minutes later I have a working electric jack on my trailer. DIsclaimer here, I did prep for the arrival this morning. 564369

I purchased this jack to replace my tired 10 year old camper jack . I ordered it at 10:00 AM Monday and as promised by Ian it was at my doorstep on Friday just in time for my weekend getaway . Installation was a breeze . I gave the product a 4 out of 5 for a few reasons . First , I was not able to see the manufacturer of the jack before receiving it . Which made name brand comparison pricing difficult . However I feel pricing was on target . Second , I feel that the jack should come with a battery terminal end connector and new mounting bolts with the hardware that was included . This didn’t pose any difficulty to me as I had hardware at hand but for some it will mean a trip or two to the hardware store . Third , once installed , at least with my truck and trailer , unless the truck and trailer are perfectly aligned and level the jack motor gets in the way of opening the tail gate . On first use I noticed it was much slower than my original but the strength made up for it . This jack had no difficulty or hesitation lifting my truck and trailer for load distribution and anti sway bar installation . I would recommend etrailer and this product . Time will be the final test of its durability . 562097

Very easy to install, and only 550 lbs tongue weight, will never break a sweat lifting my unit. Could use three packaging improvements: 1) include a ring terminal for connection of the wire to the battery, 2) include a wire tie, and 3) the manual jack handle is useless. Inside the manual opening is a 10mm nut on a shaft; the furnished handle is the female end of a 3/8 socket connector. It should be male 520924

Product arrived in the box, clearly showing what was inside, no cover box or anything, making it an easy target to steal a high dollar item. Upon unboxing, i noticed something in the lens of the light loose and dangling around, it appeared to be a circuit board of some sort. Had to dismantle the head to discover it was the "light" just flopping around inside. Put it back together and have yet to install it to see how it works. disappointing so far...On top of all that, i originally ordered the black one, was told over a week later that it was on back order until September and was offered the white one at "exactly the same price." only to find out that it was not the same price after i checked my account, albeit not much more, still more. 402138

cowling cover ( molded plastic cover) disintegrated after one year exposure to moderate North Carolina weather. The good news: I ordered a replacement cowling from etrailer but it was a bear to retro fit because of imprecise and flimsy fit. The wiring, light lense, mechanical cover did not fit . My solution was to put cowling in microwave oven to warm the material so it could be reformed by hand to make it fit.. I got it back together but it took more than 3 hours to retro fit. Spend the extra money and get a good jack with minimum 1 year guarantee. 484650

Fast shipping and faster install. Works great and moves trailer up and down fast. Only issue is the up and down arrows are reversed on the toggle switch. 545751

Jack arrived promptly as scheduled (I did pay extra for priority shipping to be sure it was here in time for upcoming trip). Installed on a tandem axle 30' travel trailer that was already hitched to truck, with no problems in about 10 min. Appears to work ok, albeit on the slow side. I didn't jack it all the way off the hitch but enough to begin lifting the rear of the truck. I can be patient as long as it does its job. Would be nice to include new mounting bolts. I also thought this model was supposed to have a bubble level on the top of the jack but nope. Can see bare wire at the end of the fuse so I'll need to tape it. Not sure there is clearance to lower pick up tail gate but the truck is turned at a slight angle now so may be ok when straight. Wish there was something to warn when near the end of retract stroke besides the clattering gear chatter. Instructions talk about waiting for breaker to reset if jack works too hard and trips. Not sure where that breaker would be located, unless they are talking internal to RV. Maybe for a different model. Product made in China. So far I'm happy with the jack and the price . was about 1/2 of local RV stores. 399956

I just received my electric A Frame jack. It looks fine and I will install it tomorrow. The only thing that I have a concern about it the handle used to crank it up or down does not fit the internal receptacle inside the top of the jack. The handle has a square hole and the jack has a hex shaped shaft sticking up. I will probably use a socket/extension/ratchet to make it work. Not very good quality control though. The over unit looks good for now. 523527

I just received this power jack for my travel trailer today. I have not had a chance to install it. I did a lot of research and read a lot of reviews before selecting this jack from etrailer. The unit seems to be of good quality and should bolt right on. I had a few issues related to availability of additional items I wanted to purchase and Bridget and Kim were extremely helpful in helping me to complete my purchase. I will not hesitate to order from etrailer in the future. 475797

Great communications with etrailer. Easy installation in minutes with few tools. Works smoothly. Seems to lift my 32' Keystone Cougar effortlessly. Now if I can only find the time to paint the rest of the tongue and frame.... 398141

Have no idea why people rate this jack less than 5 stars? But I have just put it on and tested for 1 minute. Sure it's a bit slow, but you can still drink your beer while adjusting! It has to be slow in order for gear ratio to move 3500lbs, a no brainer. And to be honest, I am a perfectionist, and it took me almost an hour to properly install...between not scratching the pole with a socket wrench and having to run to the hardware store for an end terminal. This comes with a bare positive wire. I wanted a terminal so it can be easily removed from battery each fall. 491452

Very happy with etrailer and getting the jack out to me as soon as possible. This jack is very well designed! On top is a sealed twist cap to provide access to the manual stem should you need it. My old jack you had to remove the entire top of the jack to get to it with 4 bolts that were recessed so they held water and rusted fast. Easily mounted to camper tongue, about a 10 minute installation. Yes folks, you need a terminal to attach the wire to the battery. Not a big deal, had one in the tool box. The drop leg on the jack is a great feature and one of the reasons I chose this jack. Speed is something that I saw a lot of reviews commenting about. The speed of this jack is fine! Did not seem overly slow to me. It has more power and maybe a little bit slower. So what! It will last longer because it is not taxing the jack each time you use it. Besides, what's the big hurry! Relax! You are not cracking the jack handle yourself, you are pushing a button! Great jack functioned perfect right out of the box and had no issues lifting our 7000lb Jayco travel trailer. 544823

I was a little skeptical on the purchase at first reading some reviews about this jack, Customer Service seems to be right on the ball when questioned them on a tracking BOOM it was in route and 3 days it arrived !!and when it came in I immediately opened it up and Yep as most reviews had stated about the screws on the plastic housing , which they were recessed in , wth!! Why can't they just take 3 lousy washers and use them!! I still will give this unit a 5* because that wasn't really a big deal. The 3500lb jack lifts my 3100lb Rockwood with ease, I've tested it a few times and it works awesome, some reviews said they struggled well maybe get the correct rated jack for your camper, trailer etc!! This saves my back bc of a back injury , no more cranking!! I would recommend this jack at this time, would like to follow up in the months to come to see how it holds up! Thank you etrailer!! 527083

I towed my RPOD 180 to northern NM Friday. My friends and I installed the electric jack on Saturday. We did have to go into "town" to get a couple of things we didn't have, but it was easily available at [the local auto parts store]. The installation was a snap, and the electric hitch jack has worked perfectly since then. On my way home today, I had a scary situation. The cotter pin that kept my stabilizer bar in place mysteriously disappeared on my travels. When I stopped to dump my tanks about an hour south of my camping spot, that's when I noticed the stabilizer bar was pulled out of its spot and was extended out as far as it would go. So I had to raise my trailer up and down many times in the midst of this interesting situation, which ended in me finding an Ace Hardware close by, taking off my stabilizer bar, driving to the Ace Hardware, buying a cotter pin, and installing it easily. .$85 The great part about this is that I had to use my new electric jack many more times than usual today, and it worked great each time, and my elbows (bilateral medial epicondylitis) were so thankful to not have to crank the trailer up and down and up and down multiple times today! This was a really good investment for me!! 494570

Ordered the jack in black $5.00 cheaper. Manufacturer was unable to ship the black ones. Customer service informed me there would be wait to get the jack in black, but the white was in stock. Ordered white, the jack arrived quickly, and was easy to install. People comment about some of these jacks being slow. I know that being an old man I am much slower. Installed on a car trailer with heavy tongue weight. It seems to be able to handle the weight fine. After initial install, I am happy with the jack. 373117

Great jack, works perfect on my 18' enclosed car trailer and saves my back. Light is very handy when using back up camera at night. Easy installation, fast shipping and nice follow up from company. Time will tell regarding durability. 640922

The install would have been done in 10 minutes, but I had to do a little grinding on the lower hole on the “A” fame. Pulled out the Dremel and the install was done in 20 minutes. Now if the new one lasts as long as the old one (13 years) it will be 5 Stars!! Finding and ordering on ETrailer is easy. The product arrived on time and in good shape! 639816

Ok, from my review on 1/15/19, I finally got a decent day to go to where my trailer is stored and the wife and I mounted the jack onto the trailer. All went perfect. We hooked the trailer to the hitch so we could remove the old jack without jacking the trailer up and blocking it. Anyway, the new jack slid right into place, bolt holes lined up perfect. I hooked up the hot wire to the trailer battery, remember that the jack has an internal ground and that's all you need to do. Works like a champ folks, up and down. It did sound like it was laboring but did it's job. Now we are just hoping it last a while. We will let you know. 602528

  • Comparison of Husky A-Frame Trailer Jacks to etrailer.com Trailer Jack to Replace an Atwood
  • The etrailer.com Electric Jack # EJ-3520-WBX has a 1-year warranty on its parts. Replacement parts are sometimes available however not always as common. Atwood has been purchased by Lippert so parts for their jacks are becoming more and more difficult to find. However, sometimes the parts are available from Lippert you just need to find what works with the Atwood model. The Husky Brute # HT87248 has a 1-year warranty. It's biggest advantage is the ball screw so it requires less...

  • Recommended Electric A-Frame Trailer Jack for 2008 Puma Tandem Axle Trailer

  • Recommended Electric A-Frame Jack for 2006 Eclipse Attitude 21AK Travel Trailer
  • When selecting a powered tongue jack for a travel trailer like your 2006 Eclipse Attitude 21AK it is best to over-spec the jack, meaning to select one that has more weight capacity than you absolutely need for the trailer. The Attitude 21AK has a specified weight of 6100-lbs so I suggest a tongue jack rated for 3500-lbs. This will let the jack work less hard to do the lifting it needs to do and that tends to help such items last longer. If value is a key factor in your decision go for...

  • It sounds like you have either the Electric Jack w/ Footplate part # EJ-3520-BBX or the Electric Jack w/ Footplate part # EJ-3520-WBX. If that is the case then the Replacement Power Switch part # EJ-3520-PSW is the correct replacement for you.

  • How to Determine Correct Electric A-Frame Jack for Travel Trailer
  • The correct jack will have a capacity that will surpass your trailer's loaded tongue weight, which is typically between 10 and 15 percent of the loaded trailer's weight. I looked up your 2013 Jayco Jay Feather Ultra Lite Travel Trailer and from my research it looks like your Jayco has a 4,750 lb GVWR so any one of our A-frame jacks would work in terms of weight capacity. The Electric Jack w/ Footplate # EJ-3520-WBX could be a great option; it has a 3,500 lb lift capacity, an extended...

  • Clearance Dimension for etrailer Electric Jack EJ-3520-WBX
  • I went to our warehouse to measure the etrailer Electric Jack # EJ-3520-WBX for the dimension you need to determine hatch clearance. From the center of the jack's main tube forward to the front-most part of the housing (which is actually the two black switches) the distance is 6-1/2-inches.

  • Electric A-Frame Trailer Jack for a Jayco 267 BHS
  • A popular A-Frame trailer jack is the Husky Brute # HT87247 rated for 4,500 pounds. The Husky Brute jacks use ball bearings that ride on the internal screw rather than a nut. This produces less heat and friction which can wear out other jacks. This jack also cannot be over extended which is another thing that can cause other jacks to fail. I have included a link to a video featuring this jack for you.

  • Can the Motor of the Electric Jack w/ Footplate # EJ-3520-WBX be Turned Around
  • Although the head of the Electric Jack w/ Footplate # EJ-3520-WBX cannot physically be turned separately from the rest of the jack, the mounting holes are symmetrical so you can rotate the trailer jack 120 degrees in either direction for your towing setup.

  • Wiring Electric Trailer Jack
  • We do not carry that jack so I am unfamiliar with it specifically, but to wire an electric jack in general one of the wires will be powered from a battery mounted on the trailer that is maintained by your tow vehicle's 7-way while the other wire will be the ground wire. You can test the wires by connecting them to a battery before attaching them to the trailer wiring.

  • Will Bulldog Electric A-Frame Trailer Jack Travel High Enough to Lift Truck and Trailer
  • On Bulldog electric trailer jack # BD500199 the screw (operated by the motor) travels 14 inches and the drop leg travels 8 inches for a total lift amount of 22 inches. When the jack is fully retracted it measures approximately 9-3/4 inches from the mounting surface to the bottom of the foot. When fully extended including the drop leg that measurement would be about 31-3/4 inches. You can use this data compared to the measurements of the truck to determine if 22 inches of total lift will...

  • Replacement Electric Atwood A-Frame Jack for a 2006 Weekend Warrior M-2200 FB
  • The majority of electric a-frame trailer tongue jacks will have a 3,500 lb weight capacity which is most likely what your old Atwood jack is. If not, the 3,500 lb capacity will be more than enough for you because it only needs to be rated for the tongue weight of the trailer. For this, I recommend the Electric Jack w/ Footplate part # EJ-3520-WBX which will be an easy swap with no drilling required.

It also shuts off automatically before topping or bottoming out. Other jacks will allow you to go too far with the jack but in doing so you damage the threads of the screw. It has a lifting capacity of 4,500...
