RCI's F2164 “all-in-one” fire rated electric strike is designed for offset and centerline latch entries. The F2 combines strength, (1500 lbs holding force) and convenience, (all in the box). The “Saw-tooth Adjustment Locator” design allows the installer to move the deadbolt keeper, or deadlatch ramp vertically to align with a wide variety of mortise locks with offset latches. No need to order special faceplates, adjust the strike to work with any mortise lock. Includes a faceplate for centreline latch entry. The sliding shim design adjusts vertically on the keeper to give you up to 1/8” horizontal adjustment.
