The Mul-t-lock MTL600 Hercular® Double Cylinder Deadbolt w/Decorative rosette is a high-security deadbolt system for both commercial and residential doors. The lock is made of solid brass with a chrome finish, and it features a key cylinder on both the inside and outside of the door. This makes it ideal for use in high-traffic areas or where dual access is needed. The bolt has a 1-inch throw, and it can be locked or unlocked with either key. The decorative rosette adds a touch of elegance to any door.
This Mul-t-lock features two hardened ball bearings in the bolt interlocking with the strike to increase jimmying resistance.
