If you use this ladder it will level itself to the ground automatically. When both ends of the loose bow reached the ground they are squized into the clamp and get fixed.
Clamp and bow are injection- molded pieces held together by integral hinches. This product can be an add on to an old ladder or a part of a product.
Business had no interest in this: “This is crab!”
