Video Transcript for Ultra-Fab Electric A-Frame Jack Review

Speaker 1: Today, we're going to be taking a look at and also showing you how to install the Ultra-Fab Electric A-Frame Jack, offering 18 inches of lift and a 4,000 pound capacity. Part number is UF38-944014.Now, this jack is designed to make connecting and disconnecting your trailer from your vehicle a much easier task. We've got the simple button over here that allows us to either raise or lower the jack appropriately. As you can see, the switch itself is going to have the rubber housing around it. I like that it's located down here on the bottom, so any rain or anything that might come running off of the jack, very, very unlikely to get in there and cause any corrosion at our switch. Now, it also is going have an LED light here, you can see.

This has eight LEDs on it. It's really quite bright. A lot of the jacks that we have, you'll see that they do provide some light, not a ton. This one seems to provide more light than most of them out there. That will make it easy to see your coupler, even your weight distribution setup during hookup.

Now, that light's going the be controlled with the simple rocker switch, you can see here on side, making it easy to find even in the dark.Now, to power our jack, we're going to need a 12 volt power source, so on campers and closed trailers, things like that, a lot of times there's going to be an onboard battery or you can also power it through the seven pull plug on your truck. Now, the construction of the jack really stands out above most other jacks as well. We have a full, aluminum upper housing. It's going to go down, all the way down to this point here. Compared to other jacks, most of the time, those are going to be plastic, so I really like that for the strength and durability factor.

Then, the main tube of the jack and the motor housing here, they're going to be connected up from the bottom. Where they make that seal, you'll see the rubber gasket there, so we're going to have really good protection from the elements. We won't have to worry about water and things getting in.Now, to go along with the quality construction, the outer tube of our jack, it's going to have the black powder coat finish. You can see we've got the band, it goes right around the hole here. That allows us access right into the screw so we can grease it.

That's going to really help to extend the life of that screw and our jack.Now, the front plate is going to measure six inches from outside the outside. That really helps to dissipate the weight of the trailer over a greater area. It's really going to reduce the risk of it sinking down into the ground. Now, it's not a major concern on concrete like this, but if you get in dirt, gravel, or even asphalt the weight on that inner tube can sometimes push it down into the ground. Also, this is going give us four and a half inches of adjustability. We've got four holes to choose from with an inch and a half between each one. Now, with the jack fully extended, and our foot plate fully out, it's going to measure about 32 inches to the bracket or to the mounting surface. If we we're to retract our foot plate, we're going to lose about four and a half inches, so we'll be down about 27 and a half.Now, as a safeguard, whether we're all the way raised or all the way retracted, once our jack gets to the end of its cycle, it simply stops. We don't have to worry about stripping out anything or ruining any gears. Now, if for some reason, your battery on our trailer we're to fail, maybe the seven pull on our truck quits working, you're not going to be stuck with the trailer on your truck or vice versa not being able to get the trailer onto your truck. It's provided with a 9/16 socket. You need the 3/8 drive ratchet, but that'll go right down and allow us to raise and lower our jack.To begin the installation process, of course you'll want the old jack removed from the trailer, properly chock your trailer and support it. You can see we're using a couple of jack stands. At that point, we're just going to remove the foot plate from the jack by pulling that pin we saw earlier. Set it aside. Now, we'll slide tube of the jack down in the hole in the A-frame. Now, you want to ensure that you're hole is at least two and a quarter. That's going to give you the proper amount of room. Then, we'll place that down and in.Now, unlike other jacks out there, the frange is designed so we can mount it setup to either side. This way, you can mount it so it's setup this way or the more traditional, just straightforward style mount. You'll notice those holes are oblong to make up for any variances in tolerance. Now, for the installation, you do want to reuse your existing hardware. If your hardware is messed up or if you need replacement, you just want to be sure you choose at least a 3/8 diameter bolt, and that should be at least a grade five in hardness.Now, we'll begin to snug those down. It doesn't require a whole lot of torque. You want to check the instructions to the specifications there, and also get them torqued down properly. We'll slide our foot plate back in position there. We get it pinned there. Now, as far as the wiring goes, you'll want to route it so it's going be out of the way. I like to use a few zip ties just to get it on the outer tube of the jack here. You want to run this back to your power source. You're going to see we've got a red power wire, and then the black ground wire. We've got our wires routed here where we want it. The next step is going be adding on our fuse holder. This is designed to give us protection, so we don't overload anything. This is going be the first thing to blow. We won't have to worry about damaging our vehicle, our battery, or our trailer. We cut it at about the four o'clock position there. We're going to strip both ends of that back. Just give it a good twist.And then, we're going to use part number DW05745. That's a heat shrink butt connector. And since this connection is going to be on the outside of the trailer, it's going to give us superior moisture resistance. We really won't have to worry about corrosion. We'll add it other side to the wire coming from our jack. Now, we'll use a heat source to get that shrunk down. You can use a heat gun, a mini torch, or a lighter, just be careful not to overheat the plastic. We'll kind of gently heat it. As you do this, it's kind of going to turn a little bit more clear and start to shrink down on your wire. Then, we're going to add on a 1/8 inch ring terminal. We're going to a junction box. You may need a slightly larger ring terminal if you're going on to one of your battery posts. Now, for the black wire, we'll just need to add a ring terminal on the end, and again, you want to get one that matches your setup. Now, if you have the option of running to a junction box or to a battery, I like the idea of going to the battery, just so you get a good connection there, and that will work your trailer whether it's hooked up or not hooked up to your vehicle.Now, each junction box maybe wired up differently, but what we're going to connect to is our black to ground, as are here on this end, and our power or our red is going to go to our power, which is going to be here on this end. Now, ours uses 3.8 socket. Yours might be a little bit different, but they're all usually pretty close to that size. Let's get these loosened up, and we'll get our connectors in place. Once you have your wires connected, any excess wires you might have, feel free to get that zip tied up and out of the way. You might need it later if you have to make any type of repairs.Now, we're ready to run the jack down, let it support our trailer, we can take our jack stands out. That's going to complete our look at the Ultra-Fab Electric A-Frame Jack, part number is UF38-944014.

Do you have a question about this Camper Jack?

  • A-Frame Jack Recommendation for Travel Trailer with Propane Tank Right Behind Jack
  • As far as the Ultimate Trailer Jack # 322-RDJ-2K goes the design, and more specifically the placement of the pin, is placed close to the mounting point of the jack because that is where the jack is most stable. As far as I know they are not yet making one that would work out well for your travel trailer. Your best option is a different jack that doesn't stick down so far below the trailer frame. Bulldog 3K jack # BD1550101344 is one option. Without a footplate on it measures 7 inches...

  • Upgrading Discontinued Lippert Trailer Jack 181794
  • The Lippert electric trailer jack 181794 was replaced by the Lippert trailer jack part # LC285318 with a 3,500 lbs capacity and 18 inches of lift. The Lippert jack measures 21-1/2 inches from the bottom of the mounting bracket to the very top of the jack and 10-3/4" from the foot plate to the bottom of the mounting bracket. Fully extended it measures 28-3/4 inches. Since you want a jack with a higher capacity, I recommend Ultra-Fab jack part # UF38-944014. The Ultra-Fab Jack gives you...

  • How to Determine Trailer Tongue Weight for Selecting a Powered Tongue Jack
  • The easiest way to measure your trailer tongue weight (TW) is to use a scale like the Sherline # 5780. There are other methods outlined in the linked article or you can simply take the truck and trailer to a truck weigh station. In general a properly loaded trailer's TW will be about 15-percent of its gross weight. You'll want to select a jack based on the trailer's heaviest weight condition, in other words when it is fully loaded. This will let you select a powered tongue jack with...

  • Electric A-Frame Jack that can be Mounted Sideways to Allow Tailgate to Open
  • Take a look at the Ultra-Fab Electric A-Frame Jack, # UF38-944014 with 2-1/4 inch outer tube diameter, and # UF38-944016 with 2 inch outer tube diameter. Both of these jacks could be mounted so that the motor housing is facing the front of the trailer or either side of the trailer. Mounting it to the side will give you a little over 2 inches of additional clearance. If this still isn't enough to allow the tailgate to open, it is certainly possible to have a steel plate welded further...

  • Replacement Powered A-Frame Trailer Jack for a 2005 Jayco Eagle Travel Trailer
  • There are a few things to consider when replacing a jack on a trailer. If you are replacing an A-frame jack, the mounting whole pattern is pretty much standard (3 inches apart on center). However, the shape of the mounting bracket could be round or more tri-angular. You also need to consider the tongue weight of the trailer and the amount of lift you need plus any clearances that may interfere with the jack. The best thing to do would be to get the measurements and capacities of your...

  • Troubleshooting Ultra-Fab Powered Trailer Tongue Jack
  • Some powered tongue jacks like the Husky Brute # HT87247 use the mounting flange that bolts to the trailer frame to make the necessary ground connection. Other jacks like the Ultra-Fab # UF38-944014 use a separate ground wire. Either way that clean bare metal-to-bare metal contact is essential for the jack to operate properly. A weak ground may allow the jack to function under some conditions but it is possible that it may not allow full current to reach the motor. Switches certainly...

  • Troubleshooting Electric Trailer Jack that Will Extend But Not Retract
  • There are a few possible reasons why your electric A-frame jack is extending fine but you are having trouble retracting. If the motor is not running at all when you push retract on the jack, the switch itself is likely the issue and it just needs to be replaced. If you can hear the motor running when you hit retract but are getting very little or no movement, it's possible that the jack has been over extended. This can cause damage to the threads on the nut and other internal components....

  • Powered A-Frame Trailer Jack for Use in Limited Space
  • At right you will find a link to all of our powered A-frame jacks. These vary in weight capacity, installation method and lift height. I checked the dimensions of many of these and based on the photo I have linked, the Stromberg Carlson # JET-2500 appears to require the least space to the rear - about 1-inch. I added various other dimensions to the photo to assist you in evaluating it for your application.

  • Sluggish Operation From Husky Brute Electric Trailer Jack
  • The issue you are having with your Husky Brute Electric Trailer Jack part # HT87247 could be caused by a lack of power at the battery, insufficient ground, or possibly a failing motor. I first recommend that you check that your battery is fully charged using a volt meter. If the battery is fully charged then I suggest removing the jack, sanding down the mounting surface, and then reattaching with new hardware. If neither of these fix the sluggish operation you might want to consider getting...

This jack has a lifting capacity of 4,000 lbs which will easily be enough for the tongue weight of your trailer that will most likely be right at 400 lbs.
