6000 Series Deadbolts

[Please note that ASSA has discontinued the 6000 Series Deadbolt effective immediately. Factory technical support will remain available for the remainder of the product's one-year warranty period.]

The ASSA 6000 Series deadbolt is designed to withstand any form of physical attack including drilling, prying, driving, or pulling. Its free spinning guard collars protect it from pipe wrenching while its hardened inserts guard against drilling. The 6000 comes equipped with the ASSA Hardhat™ to protect it from outside through-the-door attacks known as “ice picking.” All ASSA 6000 Series deadbolts are available with interchangeable core and feature our unique dual locking mechanism rendering them virtually pick proof.
