Semaphore Lock

Rivers Four Point Semaphore Locks are a high-security surface-mounted locking system designed for solid core double door units.

Available in Series 410 and Series 420 configurations.

Each lock utilises four 25mm x 10mm locking bars:

• One bar throws 45mm into the head of the frame
• One bar throws 45mm into the floor
• Two bars engage into receiving cups on the passive leaf, securing both leaves together

Locks are made to order based on door opening or door height.

All units are fitted with an internal lever handle that rotates downward 90 degrees to disengage the locking bars. This feature ensures compliance with the Building Code of Australia for emergency egress applications.
