Abstract: A frame for concealing the lower surfaces of T-bars surrounding an opening in a suspended ceiling utilizing inverted T-bars can be constructed so as to include tracks on at least one side of the frame and movable clips movably mounted on the tracks. These clips are shaped so as to be capable of fitting around the edges of the T-bars and engaging the upper surfaces of the T-bars in supporting the frame. At least the noted one side of the frame is sufficiently resilient so as to permit this side of the frame to be temporarily deformed in installing the frame so that the clips are hooked over a T-bar.
