This fully reversible, highly resistant electronic door strike for installation into door frames is one of the smallest strikes on the market with a width of just 16 mm, the perfect choice for narrow profiles, such as aluminum, wood or PVC. This strike is secured, i.e., in blocked position, when under power. When the power is disconnected, the strike is unblocked, and the door can be opened. This typically occurs from a control device or during a power outage. This version is supplied with a long sheet metal cover plate (250 mm).
