CRL Locknetics® Electromagnetic Overhead Mortise Shear Lock 3000 lb

• Fully Automatic 12/24V DC Selection
• 3000 Pounds Shear Holding Force
• Limited Lifetime Warranty

This CRL Mortise Mounted Shear Lock (SKU: GF3000DSMB) is a concealed, patented shear-lock designed for commercial doors and Herculite® top/bottom rail installations. Its unique "floating" mounting allows the magnet assembly to move toward the armature during engagement, overcoming gaps up to 1/4" (6 mm) without current inrush—ideal for retrofit and new construction where door/frame tolerances vary.

Once engaged, the shear lock delivers up to 3000 lbs. holding force with low operating temperatures. Key differentiators: fully concealed mortise design, patented floating action, automatic 12/24V DC voltage selection (no manual jumper), and an adjustable automatic relock (1–30 seconds). Universal hardware is included for flush or recessed door-edge installation; a "BRD" floor-mount model is available when top-rail mounting is not possible.
