发明名称 Drive-in trim system for intersecting hollow wall partitions
摘要 A two piece system for driving a piece of trim into place at the intersection of paneled hollow wall partitions comprises a retainer clip and the trim piece. The retainer clip, made of spring steel, has a first leg which is secured to the partition and a detent leg which slips between the edge of said partition and the face of an intersecting partition. A barbed leg of an L-shaped trim piece is driven between said face and the detent leg so that the lip of the barb engages the detent of the retainer clip.
