For use alone or as part of an access-control system, these locks use electromagnetic force to hold double doors closed. Control the locks with a push-button switch or keypad door control (sold separately). When power is interrupted, they instantly release. The locks must be hardwired.

Locks include two strike plates to control two doors at once. They mount under the door frame header and lock the instant doors are closed. A 5/8" thick filler plate (sold separately) is required if the mounting surface on the frame is less than 2" wide.

Optional battery backup packs supply power during power interruptions.
