Why it matters
Built for how you actually get home.
Clip-Mounted Security for Glass Doors
The Gateman GR Clip is purpose-built for glass and sash doors, using clip-type mounting hardware rather than a full mortise cut-out — a practical option for retrofitting existing glass doors in offices, clinics or retail units where cutting into the glass isn't an option.
Ways to Unlock
Keypad PIN and card key entry are both supported, so you can choose whichever access method suits the space and the people using it.
Design
An anti-fingerprint keypad surface keeps passcodes discreet by resisting visible smudges that could otherwise hint at which digits are used, and the compact, modern design is built to suit contemporary glass-door environments. Made by Gateman, a leading Korean digital lock brand.
