Dormakaba PHB 312 4-Point Locking Double Door Panic Bolt The dormakaba PHB312 is a premium, high-specification 4-point locking panic bolt set specifically configured for standard (non-fire-rated) double doors on escape and emergency exit routes. Combining high-level security with smooth, reliable egress, this set features full pushbar operations with two-point vertical rod locking mechanisms on both the active and inactive door leaves. Engineered for high-traffic environments—such as commercial buildings, educational facilities, and public spaces—the PHB 3000 series features a modular design that ensures straightforward installation and low maintenance over an extensive operational lifespan. Because this configuration is the non-fire-rated standard variant, it features built-in dogging functionality, allowing the latches to be held open during peak operational hours for free-flowing bidirectional access. Key Features 4-Point Security: Complete double door kit featuring independent two-point vertical rod locking (top and bottom latches) on both door leaves for maximum resistance against forced entry. Non-Fire Rated Configuration: Ideal for standard timber, metal, or narrow-stile aluminium commercial double doors where fire certification is not required. Integrated Dogging Device: Built-in mechanism to temporarily hold back the latches, facilitating free access during business hours. Universal, Non-Handed Design: Fully reversible components fit both left- and right-handed door configurations, simplifying on-site layout adjustments. Certified Reliability: Fully tested and compliant with BS EN 1125 standards for panic exit devices, assuring instant release under minimal pressure. Flexible Sizing: Designed for straightforward adjustment on-site to accommodate door widths up to 1300mm and heights up to 3400mm per leaf.
