Electromagnetic Shear Locks

SDC’s HiShear® electromagnetic shear locks are designed, engineered and built in America for openings that require an architecturally superior appearance. Long recognized as a cut above alternatives on the market, SDC HiShear® electromagnetic shear locks are available in concealed, semi-concealed and surface mount models. They provide high security with a failsafe locking mechanism to meet a variety of door opening applications.

The patented HiShear® design incorporates a floating armature assembly and special alloy steel locking tabs on both the lock and armature assemblies, that may be adjusted both vertically and laterally to compensate for wide door gaps and warped or misaligned doors.
