Providing increased security, reliability, and durability. DORMA offers a choice of rugged dead bolts to provide an added sense of protection. The DB600 Series are Grade 2 dead bolts with an adjustable 2-3/8 2-3/4 backset. The 1 throw dead bolt includes a hardened steel roller to prevent sawing through the bolt. The Heavy-Duty cylinders are through-bolted, with reinforced cylinder rings to protect against physical attack. Brass 6-pin cylinders are provided for security and durability. The solid steel strike plate reinforcement with 2 screws protects the door jamb against a kick-in attack.
