Many of the most advanced electronic access systems still rely on the strength and functionality of the mechanical lock hardware on the door. ND Series electrified locks feature Schlage’s most robust cylindrical design built for performance, security and durability. It is a “beyond grade 1” lock in terms of strength and can be used as part of an integrated system or as a standalone solution with a buzzer or other device as the controller.

Ideal for use on:

  • High-traffic entries as part of an access control system
  • Monitored, standalone entries using a remote switch
  • New contruction where electrified door prep can be easily incorporated
