Review on 🪜 Werner AC10-20-03 - Pair of Long Body Ladder Jacks, Aluminum, 3 Rungs, Silver by Matt Minette

They are very impressive. Very durable and extremely light. Surprisingly light weight. No problem with the Werner folding ladder and the Keller extension ladder. The best part for me was being able to use two 2x10s side by side to run around. The clip that holds the aluminum bar is removable. Leaves 2x10 flat. Is there a screw that goes through the top crossbar, bushing? For lack of a better word. This will prevent the jack from lifting off the stairs. Surprisingly I couldn't use it on the Werner Square Runner folding ladder. The step was in the way. But I used it on the basement stairs with round steps with no problem.
