Description
Product Overview
GF3000 Series shear locks feature a patented design, offering advances over any shear lock in 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.
These mortise shear locks offer the advantage of a totally concealed locking mechanism, providing superior security and appearance while allowing for normal door movement. The patented design incorporates locking "tabs" on the magnet assembly with mating grooves in the armature plate.
The GF3000 Series locks are ideally suited for commercial grade quality hollow metal doors and frames, and are designed to be compatible with HERCULITE® brand glass doors with top rail. Advances in design provide low operating temperatures, making these shear lock suitable for use in the growing demand for concealed locks in wood frames.
The GF3000TRD model is available when armature adjustment is required from the edge of the door due to flush ceiling conditions. The GF3000BRD model is available when no top rail mounting is available.
