Electric strikes provide remote release of a locked door. They allow the door to be opened without retracting the latchbolt. This occurs by the releasing of the electric strike lip (sometimes called a keeper or gate). When the door closes the beveled latchbolt rides over the lip and falls into the strike pocket. Von Duprin strikes feature all stainless steel construction, non-handed and available in 12V or 24V, DC or AC. Strikes are furnished standard in fail (FSE) secure, with fail safe (FS) optional. Strike back box is adjustable to compensate for any misalignment of the door or frame. Two piece plug connectors are furnished for ease of installation and removal during strike servicing. Von Duprin offers 22 models for wood, aluminum or hollow metal door applications. Models are UL listed for single or double fire doors.
