Video Transcript for Ultra-Fab Products Trailer Jack UF38-944016 Review

Today we are going to review part number UF38-944016. This is the ultra-fab electric A frame drop leg jack. This jack has a 4000 pound weight capacity and an 18 inch lift. This jack uses a 12 volt motor to help power the jack and eliminates the need for any hand cranking. It has, right over here, this built-in toggle switch for easy operation and it is covered for weather proof protection. It does have an integrated circuit breaker to prevent motor damage.

It does use all steel gears which are strong and durable and if youll notice, right here on the front, here is a very large front light that makes it simple to set up your camper at night time. It does use LEDs which will last longer and use less energy than the incandescent bulbs and if youll notice the way that lamp is positioned it will actually direct the light downward to better focus on the ground in the area you will be working in.Just by chance if you do run out of power and you do need to operate the cranky, you can do it manually, at the very top, it has a plug that you can remove and it includes this 9/16 deep well socket. You can just put it in there and insert on to the drive collar just like that and then you can crank it with a ratchet and if you ratchet it clockwise it will retract the jack, if you ratchet it counter-clockwise it will extend the jack and then when you are done you can put the cap the rubber plug right back on there. This is an easy bolt-on or a weld-on installation for A frame trailers, the hardware is not included.It does have mounting holes, right here that you can see and it will mount on either a 2 inch spacing or in a 2 inch spacing. It does use an extra-large foot plate to provide excellent stability, it is 6 inches in diameter and this foot plate does extend 5 extra inches.

In other words if you would pull this pin out, remove the pin you can see that you can actually raise it up into many positions it will go all the way to 5 inches and when you find your right position, just go ahead and put your pin right through, put the clip on then you have it in the position you need it.On the top here it uses a die-cast aluminum cap to resist corrosion. The whole jack itself is a steady steel construction with a black powdered coat finish. It does also come with the besides the deep well socket, it does come with this inline fuse holder in which you would that far as if youll notice it has a black wire and a red wire. Red would be for your 12 volt power black would be for your ground and what you want to do is can go ahead and ground this to a good clean ground, your power wire what you would want to do is use this inline fuse holder and connect your power wire to one end of this inline fuse holder, the other end would connect to your power source so that way you would have a fuse right here and this black portion will protect this jack.Im going to hook this up to a power a 12 volt power source I have here to show you how it will operate. I do want to first give you some dimensions, the bracket height, right now the jack is in a fully retracted position and the foot plate is in the very lowest fully retracted position.

So if you measure from the foot plate to the bottom of the mounting bracket it will be 9 inches, thats retracted. With the footplate retracted, it does have an 18 inch lift so that would mean that if you fully extend this out and if that footplate is still in the same position it will give you 27 inches and if it is extended all the way out and then you let the foot plate all the way down 5 inches then youll have a total of 33 inches extended, with the foot plate extended. Again the lift capacity on this is 4000 pounds. The two diameters, the outer tube diameter is two inches. The inner tube, right down here, diameter is 1 inches.

It does come with a one year warranty.I dont want to want to do now is just hook up my 12 volt power source. We are going to hook the 12 volt power to the red wire then I do have a ground here that we are going to hook to the ground wire and then youll notice right over here is a nice toggle switch red in color. If youll notice the very bottom, youll see those LED lights light up. Turn them off or turn them on. Then right here your toggle switch that will operate your jack. So if you you can see its extending out. If you take your finger off, you do have to hold the switch to be able to operate in other words if you do remove the hand it will stop the motion in the jack. That will extend it all the way up and this will push it the other way and it will go all the way down. There it is fully retracted.That should do it for the review for the part number UF38-944016. This is the ultra-fab electric A frame drop leg jack with a 4000 pound weight capacity. .

I just installed the Tongue Jack last weekend. The install was very simple although I added a simple anti-theft device in the form of a kill switch. I placed a switch inside my trailer that allows me to disconnect the power to the jack while it is stored at my shop. Installing the jack was as simple as bolting it onto the trailer and attaching the wires! 97053

I received the product in a timely manner. The installation when without a "hitch". I tried to angle the motor head so the tail gate of my truck would come down but just wouldn't accommodate it. The only suggestion I would have to the manufacture is to integrate the fuse link with the main wire to avoid making a manual connection that might later disconnect or short out. I was a little surprised at the slow speed of the lift, but it certainly has the power to raise both my trailer and truck to install the equalizer bars. Recommend using a 4x4 crib under the foot plate just to minimize travel time or length. Overall seems to be an excellent product and service from etrailer. 71385

Received item quickly. etrailer upgraded shipping for me with no additional charge. Haven't had chance to put jack on trailer yet due to time. I did inspect the items. Package for jack was slightly damaged but I expected that with the weight of the jack. Box that both Lynx leveling kit, covers, and jack came in was not damaged. Will be putting jack on this weekend to give it a full try.106664

  • Ultra-Fab Electric A-Frame Jack # UF38-944016 for 2009 Keystone Outback Toy Hauler
  • According to the information I was able to find, the Ultra-Fab Electric A-Frame Jack you referenced, part # UF38-944016 would be a good choice for the Keystone Outback Toy Hauler you mentioned. The jack has a 3500 lb lift capacity, which is plenty for the listed tongue weight of the toy hauler, plus anything stowed on it. Among the many features of this jack, I like the fact that is uses LED lamps for long life as well as the fact that a 9/16 inch socket wrench can be used in an emergency
