Why it matters
Built for how you actually get home.
A Slim Lock for Narrow Door Frames
The Gateman GR Sash is designed specifically for narrow door frames where standard digital locks won't fit — sash doors, internal room doors, and aluminium-framed doors in homes, offices and rental units that a bulkier lock body simply can't be mounted on.
Ways to Unlock
PIN and RFID keyless access, kept deliberately simple with no unnecessary complexity layered on top — a lock built to solve one narrow-frame problem well rather than trying to do everything.
Security & Power
An auto-lock function, intrusion and tamper alarm, and low battery alert system come standard, along with emergency power support if the batteries run low.
