Abstract
A folding ladder assembly having a door, a frame, and a strut connecting the door and frame. The strut comprises a first end and a second end opposite the first end. The first end of the strut is attached to the door via a strut stop bracket. The other end of the strut is attached to a stationary mounting plate, which is attached to the ladder opening frame. The strut is attached to the strut bracket via a strut standoff using an E-clip retaining ring. Optionally, the strut standoffs are riveted to the strut stop bracket and the stationary mounting plate. The strut stop bracket is optionally formed having a double bend to form two substantially parallel portions connected by a third non-parallel portion.
