Schlage GF3000-MBS Mortise Mounted Shear Electromagnetic Lock w/ Magnetic Bond Sensor

Be the first to review this product

The GF3000-MBS Shear Lock features a patented design offering advances over any Shear Lock on the market. Unique mounting features provide a “floating” action of both the lock assembly and the armature. This design allows the magnet assembly to move towards the armature during the locking process. In this manner, the GF3000 is able to overcome gaps of up to 1/4 inch without current inrush. Once engaged, the Shear Lock provides 3000 pounds holding force, without high operating temperatures normally associated with other Shear Locks. A microprocessor-based control module provides advanced electronic features. This circuitry automatically senses and adjusts input voltage, allowing for operation from 12 to 24 volt DC power sources. The mortise Shear Lock offers the advantage of a totally concealed locking mechanism, providing superior security and appearance. The patented design incorporates locking “tabs” on the magnet assembly with mating grooves in the armature plate. While the strength afforded by this design is a major advantage, the flexible mounting features are as important. This design allows for normal door and frame movement.
