DORMA offers a choice of rugged dead bolts to provide an added level 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 throughbolted, 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.
