Security Door Controls

SDC’s 55 series 3/4” latchbolt electric strikes are heavy duty, designed for installation in hollow metal frames for access control of cylindrical locksets, mortise locksets with or without deadbolts and mortise exit devices. 55 series strikes accept 3/4” throw latchbolts and up to 1” throw deadbolts. The choice of six application faceplates eliminates the need for centerline relocation, making them ideal for new or retrofit, high security access control applications. 55 series strikes retrofit existing ANSI 47/8” strike prep – no centerline relocation required.
