7140 Electric Strikes with a 4-7/8” faceplate are designed for Adams Rite deadlatches or cylindrical locksets with ½” to 5/8” latchbolt projection. For use in hollow metal or wood doors and jambs.

Electrical actuation unlocks strike jaw, releasing latchbolt so door can be opened without operating latch itself. Extremely compact mechanism fits into aluminum jamb sections as shallow as 1-5/8”.
