Abstract
A multi-angle hook fastened to an extension member, that is used to stop the extension from completely pulling out of the frame it sits in. When fully extended, the multi-angle hook allows at least three different holding positions, seen as three different angles that the extension sits at while using the multi-angle hook as its fixed point of pivot. The multi-angle hook is a metal, plastic, or wood plate bent along several parallel lines, across its width, at varying angles. An L-shaped hinge which is used to secure a side rail-less frame member to another frame member, to avoid undue stress on the side rail-less frame member. The L-shaped hinge is a metal, plastic, or wood plate which substantially conforms to a portion of a side rail-less frame member.
