Abstract
An electric strike which provides vertical adjustability of the position of the strike relative to the latch bolt in the closure with modification to the doorframe on the dust box. A ramp element on the strike housing is slidably adjustable relative to the strike housing and is securable at the time of installation to align with the center of the latch bolt. The ramp element has a channel to allow entry and exit of a latch bolt having a dead latch. A keeper engages the dead latch and maintains it in a retracted position when the closure is locked and is released when the electric latch solenoid is energized. A travel limiting foot limits rotation of the keeper so that the latch bolt may transition from the keeper to the ramp element without interference.
