Secure high-traffic commercial entrances with the robust, tamper-resistant Security Door Controls SDC 55-EU mortise deadbolt. Engineered for dependable access control, this heavy-duty deadbolt accepts 0.75" latchbolt throws and up to 1" deadbolt throws, making it compatible with many cylindrical and mortise locksets.
