National Marker N150771 Zinc Chain Bolt with Strike

Product Description

The NATIONAL MARKER N150771 is a zinc chain bolt assembly designed for door security applications in residential and light commercial settings. The unit features a steel case and strike with a die-cast zinc bolt body and a malleable iron reversible bolt measuring 5/8 inches square. The bolt throw extends 3 inches and ships complete with mounting screws, a bolt rim, and both mortise and rim strike plates. Installation requires only basic hand tools, making this a straightforward addition to a door prep or hardware replacement job.

This chain bolt is suited for interior door security applications where a secondary locking mechanism is needed. The reversible bolt design accommodates both left-hand and right-hand door configurations without additional hardware. The included strike hardware supports both rim-mount and mortise-mount installation scenarios, giving the installer flexibility depending on the door frame and jamb construction on site.

Installation Notes

Installation is performed by a qualified carpenter, locksmith, or general contractor using standard hand tools. Power down any electric strike or access control system before beginning work if integrating with existing hardware. Follow local building codes for door hardware placement and fastener requirements. Ensure the door and frame are properly aligned before final strike positioning to avoid bolt binding.
