Abstract
A trim plate is disclosed that includes a base plate, a folding hook arm pivotally attached to the base plate, and a weight-bearing truss that supports the folding hook arm. A first end of the weight bearing truss is pivotally connected to the hook arm at about the middle of the hook arm and the second end of the truss is positioned in a primary slot in the base plate. Two secondary slots in the base plate are positioned on either side of the primary slot, and pins extend perpendicularly from the base plate end of the truss and fit in the secondary slots for sliding therein whenever the hook arm is open or closed.
