Ultra-Fab Products 48-979004 Ultra Stacker Jacks

Got these for a neighbor who wanted to use then for their camping trailer. Later said they worked great, easy to store, lightweight and sturdy. After I got off the phone with them I thought that was the perfect call and decided to give this product a five star!

Using these jacks to support my boler camper while camping. They are easy to use and pack up pretty small. They gave us the opportunity to stabilize our small camper without having to drill holes into the frame (which I didnt wnt to do) they got pretty corroded over the winter outside but they was to be expected from anything other then stainless steel.

Took all the sway and bounce out of my bumpouts. I know there's the "Never, ever, put supports under your slide outs" crowd. We're not lifting the bumpouts, people! We're SUPPORTING them. Now, just let me enjoy my permanent site trailer....ahhhh, PERFECT!

The jacks are made from very strong yet lightweight and non rusting cast aluminum so they should last pretty much forever. When living in my RV like I do, storage space is at a premium so I really like the way the jacks can have the screw mechanism removed so that the frames can stack inside each other in the box. The screws are then positioned at each corner of the box they came in so the whole package is very compact.When in use, the jacks do exactly what I want them to do. They were purchased to make the RV floor feel more stable, especially when previously the grandchildren used to visit and treat the floor like a trampoline. The RV feels a lot more solid now on windy days as well. They were easy to install and I am now thinking I will purchase another set to use to stabilize the steps from my RV using 2 of them and use the other 2 to add additional support at the mid point of the RV frame where the wheels are.This is a good product and good value for the price paid.

Great for stabilizers under small camper. Of course they aren't as strong if extended.
