The Locknetics by Schlage GF3000SM shear lock features a patented design offering advances over any shear lock on the market.

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.

This surface shear lock offers maximum versatility in application. The GF3000SM model provides a low profile, surface mount lock for outswinging doors. The GF3000TJ model provides a low profile, surface mount lock for inswinging doors. It provides a unique mounting solution with no brackets needed, which are standard with direct pull magnets. The GF3000SM and TJ models feature a black anodized housing with the choice of modular finish plates.

Model

GF3000 Adjustable from top edge of door.

GF3000TJ Top Jamb Unit (inswinging doors) Magnet mounts on inside top jamb. Adjustable from top edge of armature.

GF3000TRD Mounting assembly which provides armature adjustable from the latch edge of the door.  Recommended with zero clearance condition between top of door and ceiling.

GF3000BRD Mounting assembly to mortise armature into bottom rail of door. Magnet is installed in floor/threshold. Provides solution when no top rail is available.

Options

DSM/MBS Door Status Monitor/Magnetic Bond Sensor

Surface mounted magnet mounts under header and surface mounted armature assembly mounts into door just under magnet assembly. Air gap adjustment is from top of door by allen wrench.

Door Status Monitor(DSM)The optional DSM provides a dry set of contacts for monitoring “door open” or “door closed” conditions.

Magnetic Bond Sensor (MBS) The optional MBS provides a dry set of contacts for monitoring “door locked” or “door unlocked” conditions. The MBS measures the magnetic holding force between the armature and the magnetic coil. Poor magnetic bond is the result of low voltage, foreign material between the surfaces of the magnetic coil and armature, or improper alignment of magnet and armature.
