A latch is a piece metal that extends into the doorjamb to secure it shut. It is operated by a handle or knob on the inside of the door, or a thumb turn on the exterior side of the door. A deadbolt can be used to secure a latch and prevent intrusions from breaking through the glass of the door.

The strikes have a unique design that allows the latchbolt and keeper to slide into the pocket without causing damage to the faceplate of the doorjamb.

The strike has an internal ramp that raises the latchbolt and keeper whenever it receives an electrical impulse from a controller or reader. The retracting of the keeper as well as latchbolt raises them on the ramp, thereby locking the door. When the door is shut, the deadbolt stays retracted and the latchbolt retracts into the keeper.
