Quick Overview

MODEL 6550

Electronic Vault Lock

The Electronic Vault Lock from Sargent and Greenleaf combines the security and convenience of the S&G electronic lock with the durability and dependability of the traditional S&G mechanical vault lock. The result is an innovative solution that once again shows why S&G is the most trusted name in vault locks. The Electronic Vault Lock is ideal for vault doors, high-security safes, night depositories and applications that include a secondary lock override or separate service door.

Roller Bolt Option: Opens to provide a path into the lock case into which a snubber bar can move; designed for indirect drive applications
