Continuous Security Locking

Storeroom Function Lock Cylinders (ANSI F07) ensure that high-value storage areas, server rooms, and utility closets are never accidentally left unlocked.

Mechanical Latch Kinematics

  • Outside Lever: Permanently rigid and inoperative.
  • Entry Method: Inserting and rotating the physical key temporarily retracts the latchbolt for entry; removing the key leaves the door immediately locked.
  • Auxiliary Deadlatch: A secondary deadlocking plunger prevents credit-card shimming attacks.
