Abstract
A vision frame assembly for use in fire-rated structures such as doors and alls. The frame assembly includes a pair of opposed frame members that snap-fit into a plurality of resilient latching clips mounted in the door or wall. The latching clips include mounting members to mount the clip to the door or wall and spring finger elements having differing lengths. The unique configuration of the spring finger elements makes the frame assembly adaptable to wide tolerance variations from different manufactures of doors, walls, and other fire-rated structures.
