Mul-T-Lock Hercular Deadbolt

The Mul-T-Lock Hercular deadbolt represents the premium tier of Mul-T-Lock's residential and commercial deadbolt line. It features the patented Interactive+ cylinder platform, a free-spinning hardened anti-drill guard, and a reinforced bolt assembly. This is the lock specified when maximum resistance to manipulation, drilling, and forced entry is required.

The Hercular is the deadbolt you install when standard high-security is not enough.
