The GGH Double Door Electromagnetic Lock is designed to provide secure locking performance for commercial double door access control systems. Engineered with an anodized housing and a flame-retardant encapsulated lock core, it delivers a holding force of 1,650 lbs. (750 kg) per door leaf while providing reliable operation in demanding environments. The integrated LED indicator and lock status signal output allow convenient monitoring when connected to compatible access control systems, while the anti-residual magnetism design enables fast unlocking within 0.5 seconds after power is removed. Tested for one million operating cycles and a 240-hour salt spray exposure, this lock is suitable for glass, wood, metal, and fire-rated door installations.
