Trimco 3820626630 Ul Semi-automatic Flush Bolt

Product Description

The TRIMCO 3820626630 is a UL-listed semi-automatic flush bolt designed for installation in metal doors. Flush bolts are surface-mounted or mortised hardware components that secure the inactive leaf of a pair of doors without requiring a separate locking cylinder. This model operates semi-automatically, meaning the bolt extends or retracts through a spring-actuated mechanism that reduces the manual steps required during operation. At 16.7 inches in length, it is sized for standard commercial door applications. Licensed door hardware installers and commercial locksmiths are the primary trades that specify and install this hardware in new construction and retrofit projects.

This flush bolt is intended for use on the inactive leaf of metal double-door assemblies, commonly found in commercial and institutional buildings. Semi-automatic flush bolts are frequently specified in corridors, stairwells, and entry vestibules where paired metal doors must meet fire or security codes. The UL listing makes it suitable for applications where code compliance documentation is required at the hardware schedule level.

Installation Notes

Installation should be performed by a licensed door hardware technician or commercial locksmith familiar with ANSI and UL hardware standards. Secure the door in a stable, open position and confirm all electrical or access-control power to the door assembly is off before beginning work. Follow the hardware schedule and door prep specifications to ensure the bolt aligns correctly with the strike or floor strike. Consult applicable building and fire codes for required clearances and operational testing procedures after installation.
