With its truly unique design the MUL-T-LOCK Hercular deadbolt is truly spectacular. The Hercular is reinforced in just about every way possible. From a UL437 Listed Cylinder, to strong latch, to Bolt Bearing Mechanism, the Hercular Deadbolt will stop almost any attempt at forced entry. Strength usually does not mix with Flexibility. Not in the case of the Hercular, since it is the only Grade 1 Deadlock with an adjustable backset. This makes the Hercular deadbolt a true high security lock that exceeds all high security standards.

LET US SHOW YOU HOW STRONG THIS LOCK IS...

We counted at least 20 blows with a crow bar or hammer or both and they were unsuccessful. The lock still works perfect! This was the 4th attempted burglary at this car wash. The first one was with just a knob lock and they were successful by spreading the door and frame. With the Mul-T-Lock Hercular Deadbolt its virtually impossible to pry/spread the door from the frame.

Anchor Security & Locksmith highly recommends Mul-T-Lock as high security hardware for your home or business.
