Usage
Designed for commercial, industrial, and institutional applications, this flush bolt set excels in settings where fire protection and secure egress are critical. Ideal for warehouses, manufacturing facilities, data centers, and public buildings, the bolt automatically engages when the inactive door closes, keeping the door latched even when the active door is opened. In the event of a fire, the thermal lock mechanism activates, ensuring the door remains locked under high‑heat conditions, thereby containing fire and smoke spread. The compact design integrates seamlessly into door frames without protruding hardware, preserving aesthetic continuity while delivering robust security.
