Von Duprin 050171-32 LBR (Less Bottom Rod) Fire Latch and Strike Kit

The purpose of the auxiliary fire pin assembly is to keep double doors in alignment during a fire. In a fire, the bolt extends from the auxiliary fire pin into the strike hole in the opposite door leaf. The black cap visible on the face of the auxiliary fire pin and the strike hole plug must melt in order for the bolt to extend.
