Electric Strikes and Rim Locks

How to choose an electric strike or rim lock

Strikes and rim locks keep the door's mechanical handle working, which suits offices that want normal exit by lever or knob.

• Fail-safe or fail-secure: fail-secure models stay locked during a power cut and suit stores or cash rooms. Fail-safe models release, which escape doors often require.
• Frame and latch fit: check the strike's face plate size and the latch depth against your existing mortise lock.
• Door feedback: a strike with feedback reports whether the door is actually closed.
• Retrofit or new door: a rim lock mounts on the surface and needs less frame cutting, which helps on older doors.
• Voltage: confirm 12 V or 24 V operation against your power supply.

For doors where a strike will not fit, look at magnetic EM locks, and pair any lock with an exit button.
