SDC 1560 Series - Concealed Electromagnetic Shear Locks 2000lbs and 2700lbs Holding Force

SDC’s HiShear® electromagnetic shear locks are designed,engineered and built in America for openings that require an architecturally superior appearance. Recognized as a cut above alternatives on the market, SDC shear locks 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. Advanced electronic circuitry incorporates a door alignment relock sensor as well as an automatic sensing dual voltage input. Noise dampeners greatly reduce the noise associated with locking and unlocking when compared to other shear locks on the market.
HiShear® magnetic shear locks are ideal for use on commercial grade hollow metal and wood doors, metal frames and Herculite doors with top rails.
The innovative 1560 series concealed electromagnetic shear locks are available with 2000lbs and 2700lbs holding force for standard 13/4” to 2” frames with internal electronics, as well as narrow 11/4” to 11/2” frames with external electronics.
