SDC Hi/Shear® magnetic lock utilizes several of the most innovative and unique design attributes. The Hi/Shear is the magnetic lock that gives those who want a better shear lock all the latest features.

The SDC Hi/Shear® is a totally concealed, high security, failsafe locking mechanism with superior appearance. The patented Hi/Shear® electromagnetic lock 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.

Hi/Shear® magnetic locks are ideal for use on commercial grade hollow metal and wood doors and metal frames and Herculite doors with top rails.

Hi/Shear® Magnetic Lock Features

Door Static and Alignment Sensor
The door static sensor ensures that the door is at rest and aligned, before the magnet is permitted to energize, eliminating potential for lock misalignment

Lateral Alignment Adjustment
Lateral adjustment of shear tabs to compensate for warped or misaligned doors, permitting accurate locking.

Vertical Alignment Adjustment
Vertical adjustment of the armature compensates for wide door gaps.

Floating" Assembly
A unique "floating" action makes for easier armature lift when the magnet is energized and provides the ability to overcome wide door gaps.

2000 or 2700 Lbs Holding Force
2000 or 2700lbs. of holding force without current inrush or high operating temperature normally associated with shear locks.
