Greater security is provided by the 0.625” diameter stainless steel bolt. The bolt rotates freely, making attempts to tamper or cut extremely difficult.
SPECIFICATION GRADE SOLENOID
All Spacesaver® lock solenoids are manufactured by SDC to precision specifications. SDC solenoids are capable of superior overall performance in both force and longevity, providing years of service compared to commercial grade solenoids.
MECHANICAL RELEASE FUNCTION
When used with a mortise key cylinder (not included), the key cylinder is used to manually override the solenoid.
FIELD ADJUSTABLE AUTO-RELOCK SWITCH
The automatic relock switch keeps the bolt retracted while the door is open. The door depresses the ball switch assembly on closure, causing the bolt to project automatically, locking the door. In addition, the ball switch assembly is bidirectional, permitting the locks to be used on swinging and sliding doors.
