Document: Little Giant 12106 RevolutionXE Ladder Leg LevelerThis item works exactly as advertised and is very useful. Buy two so that you can level both A-frame pairs.
Absolutely a necessary tool for your ladder. This is well-built, sturdy and easy to use. My ladder is a G******, not Little Giant but this accessory fits well and does the job. It stores well attached to your ladder so it's always at hand when needed and doesn't take up space or get in the way when using the ladder normally. I highly recommend this product for homeowners and professionals.Little Giant 12106 RevolutionXE Ladder Leg Leveler
As noted by other customers, the plastic leg is angled in the WRONG direction, so you have less material making contract with the ground. It specifically states in the instructions the leg should be flat with the ground. You can't do it with this extension. How they could let this get out the door is beyond me.
great addition to my Little Giant!
the little giant leg levelers were just what we wanted..
Use on any aluminum Little Giant ladder
I don't know what that's all about, but it would be an easy fix for Little Giant to make.
Works just like it should. A nice addition if you have the Little Giant ladder. I would buy this again.
We already own one Little Giant and needed another. Found the price point and decided to buy.
works so good I bought 2 so that i can level both sides of my little giant ladder in step ladder mode.
