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

Today we're going to be taking a look at the Ultra-Fab Electric A-Frame Jack with 7-Way Plug. Part number UF38-944037. This 12-volt jack plugs into your vehicle's 7-way connection for power. It's perfect for saving your trailer's battery or for trailers that don't have batteries. When fully retracted, from the plate to the mounting bracket, we have 9-1/2 inches. With it fully extended, in that same measurement, it gives us 27-1/2 inches, giving us a total of 18 inches of lift. The 12-volt motor features all-steel gears, so it's going to provide long lasting strength and durability. The dual side lights make late night hookups a snap. A 9/16 deep well socket is included that you can use with any 3/8 ratchet so you can operate the jack without power.

Hidden in our tube is a Zerk fitting. That way we can add grease as needed to prolong the life of our jack. It also comes with a cover. You won't have to pick up a foot plate because one is included. The whole thing is made out of a sturdy steel construction with a black powder coated finish so it's going to resist rust and corrosion. When not in use, our 7-bolt connection can be removed and bundled up and it has a hoop and loop keeper.

Then you can just bundle it to your jack. It's a very easy installation. It can be bolted on or welded on. You just want to be sure to hold on to your old hardware or you'll have to pick some up. It's built with two sets of mounting locations.

That way it'll fit 2 inch and 2-1/4 inch spacing. The Ultra-Fab Jack features a 3,500 pound weight capacity. That's going to complete our look at the Ultra-Fab Electric A-Frame Jack with 7-Way Plug. Part number UF38-944037.

The electric A FRAME jack with the 7 -Way Plug is the second one that I ordered.The unit is most helpful as it has the electric hook up to the plug in and do not require an extra battery. Very quick to install.I would recommended that you include with the star locking washers 3 new mounting bolts. When removing one of the original mounting bolts it broke. 521350

I liked the first one so much that I purchase another one for my other trailer

I called With a somewhat blurred picture was able to determine the part number less than three minutes on the phone. Jack was delivered in five days fit perfectly. Thank you 738301

- UF38-944037

At one year old this performs as expected meaning "Well" it is on a trailer exposed to elements and has not flinched to work well thanks 719702

- UF38-944037

We love this jack. Works every time. Would recommend this. 713876

- UF38-944037

We loved the jacks ease of use. But I over extended the jack unknowingly and stripped the PLASTIC GEARS. I just contacted the company (Ultra fab ) and they said it should not have happened and immediately they shipped me new gears ( STEEL) . We will be putting them in this week. If the gears had held up I would have given this 5 stars. Hopefully this won’t happen again with the steel gears. 705070

Good product, use as directed. 677692

- UF38-944037

Item was shipped quickly. Installed it on a 20' enclosed cargo trailer. Works like a charm! Love the feature of using the truck 7 pin plug for power instead of a dedicated battery. 638644

I used this on a 1972 Argosy and surprising it fit into the original hole pattern. It works AWESOME--I love it and would highly recommend it to anyone!! 496784

- UF38-944037

works great would do again. Thanks 462217

- UF38-944037

The jack works really well! There was an issue with the first one I received being damaged in shipping but etrailer spoke directly with the manufacturer where it was drop shipped from and they immediately sent a new jack. Wonderful customer service from etrailer and Ultra-fab. 461795

- UF38-944037

Works just as expected. Have a 20 ft trailer with a 38 horsepower tractor. About 5000 lbs total. Will lift with no problems. Love the 7 pin connection. No extra battery needed. 460021

- UF38-944037

Works great. Put it a Jayco and when I traded it in kept it and put on my new Summerland. It does all that I hoped and has made hooking up and unhooking a breeze. It has made my setup quicker and easier. I am glad I purchased it. Also, your price is so much lower than anyone else for the same jack. I love that is power by my tow vechile and I can still use it if my battery on my trailer dies or is discharged. I would highly recommend it to others to purchase. David. 448514

Not good it stop working 437671

- UF38-944037

this is my second one, for a second trailer. I am fully satisfied with the first one. I have learned to put a block of wood under it to give additional height on uneven ground, and to expedite the process. Easy installation. Great product. 434770

- UF38-944037

installed on a "Casita" 17 ft camper-Works GREAT!! 430766

- UF38-944037

Easy enough to bolt on, but it doesn't work. It blew my fuse. It also hangs so low that I could get over a speed bump. Ruined a trip. Total waste of money. Hope they take it back. 413255

- UF38-944037

The Jack works great. However there is no documentation as to how much current draw it uses and I was frequently blowing fuses. I finally replaced and in-line fuse with a self setting circuit breaker and I never had a problem after that. Also after just a short time the lights on exterior stopped working. 409545

Only drawback is that the plate that mounts to the frame is circular. I had to move the battery holding tray on my '08 Jayco in order to mount it. 407350

- UF38-944037

Glad to have it. EASY installation. Going camping this weekend to try it out, on my 18 foot camper trailer. Nice to not have to do all the hand cranking. Suggested the package include new bolts, rather then requiring use of old bolts. Awesome to just plug it into my vehicle and raise and lower. Nice feature having lights. I recommend it at this time. 405204

- UF38-944037

Don't know haven't installed yet but it looks good quality comes with 2 year warranty so I guess it's good I will do another review once I use it 397364

- UF38-944037
