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. Show more
