RAMEJ-3550-BBX Electric A-Frame Jack with Single Wire Hookup - 3.5K Capacity

Seems to be a solid product not much for instructions on wiring.On the jack I received the blue wire is the hot + and black is the negative - the jack will raise and lower either way you hook it up but the led light will only work in my case blue to the positive and black to the negative. Hope this helps. I raised and lowered the jack 20 + times just make sure it held up. I did get a water proof cover.

Good product, good price, fast shipping

I dont even know of this is a decent jack, because I can't get it to work. The instructions have only 6 steps, 5 of them are about installing the jack, only one for hooking up the wiring. And after hours of additional research, I think that step is wrong, directing you to connect the black wire to a fuse (not included), rather than the blue. Also, there was no hardware included, and no list of tools or supplies needed. This is only good if you're an electrician.

Installed this electric jack this past weekend. Minor problem in that lower hole through trailer frame was VERY slightly smaller than jack housing shaft. Used a small grinding wheel in an electric drill to grind around the lower hole and in less than 3 minutes everything dropped into place. This jack is not noisy. It is a little slow, but not to the point of being a problem. I hope it lasts for a long time. I also wish I had installed it along time ago. I am a senior citizen and using the crank handle on a manual jack had become a problem, especially in the Texas heat. Now I just push the up/down button and this jack takes care of the work.

good price and fast d

I knocked this down a star because the installation instructions are not well written. The website and the directions specifically say that only ONE wire connection is needed. But the unit has 2 wires. It doesn't work at all unless both are connected. So black wire to positive terminal, blue wire to negative and it works perfectly!

Exactly right part to replace my damaged jack

The jack does exactly what it should do. Very powerful. The light has never worked…. a little disappointed.
