Dormakaba PHB 308 3-Point Locking Double Door Panic Bolt The Dormakaba PHB308 (PHB308C) is a high-performance, fire-rated commercial escape system engineered specifically for double-leaf doors in high-traffic or public buildings. Providing maximum safety under emergency conditions and high security when closed, this modular set delivers a combined 3-point locking system across both door leaves. The assembly consists of a 1-point locking rim exit device on the active leaf paired seamlessly with a 2-point locking vertical rod device on the inactive leaf. This configuration guarantees effortless, panic-free egress across the full opening width while preserving structural fire-door integrity. Key Features Combined 3-Point Security: Distributes absolute latching stability over the double door set—utilizing a heavy-duty steel horizontal rim latch on the active leaf and dual vertical steel latches on the inactive leaf. Fire-Rated Compliance: Fully approved for use on single or double fire-rated and smoke-check timber and metal doors. Anti-Thrust Protection: Features an integrated security anti-thrust mechanism that prevents unauthorized latch tampering or forced entry from the exterior. Universal, Non-Handed Design: The mechanism is fully non-handed, making it compatible with both left- and right-handed door configurations, simplifying on-site installations. Sleek Conture Styling: Designed to eliminate visible fixings for a clean aesthetic that complements modern architectural spaces without compromising heavy-duty utility.
