8200 Series

Mortise Locks

With its innovative, multi-functional lock body, the 8200 Series Mortise Lock, is considered the industry benchmark for all mortise locks on the market today. It is also the strongest and most durable—far surpassing ANSI/BHMA A156.13 Series 1000 Grade 1 standards in independently verified testing—for additional resistance against vandalism and unauthorized entry.

The electromechanical version of the 8200 Series Mortise Lock operates from 12 to 24VDC and can be used in stand-alone applications or as part of an integrated access control system. Featuring EcoFlex technology, the electromechanical version dramatically reduces power consumption by up to 96%, as certified by GreenCircle.
