B600 Series Grade 1 Indication Trim

Patented, 180-degree design applied to Schlage's Grade 1 fire-rated deadbolt in five functions, single- or dual-sided, provides optimal protection and lasting durability.


Schlage B600 deadbolt with lock status indication is unlike any other. A large viewing window wraps three sides to give 180-degree visibility. Privacy solutions include a coin turn option ideal for thicker bathroom stall doors. Double cylinder locks are ideal for storefronts and other entryways. Most functions can be ordered in single- or dual-sided indication trim and are made to be just as durable as the standard Grade 1 lock and just as beautiful. The sleek design is offered in 10 finishes. 

B600 features the patent protected Everest 29 as the default keyway but are upgradable to Primus levels of cylinder security. But strength in the key system is only half the story. These tough deadbolts are Schlage strong, with anti-pick and tamper-resistance built in. With an impressive list of security features and a wide variety of functions, the Grade 1 B Series is Schlage's best deadbolt.
