One Million Key Changes

Part of our Million Lock Series, this cam lock features a dimple key with one million possible key changes and is available both in a standard (GS-GL20-BL-D) and master key (GS-GL20-BL-B) option.

The dimple key on this cylinder lock for door security is reversible and can only be removed when locked. Simply turn it 90° to lock and unlock.

We designed these keys to be compatible with other locks in our Million Lock Series, if desired, so that one key can open multiple locks.

Safe & Convenient Installation

Installation of this glass door lock is straightforward and simple; the only drilling requirement is a single round hole.

This glass cabinet lock includes shatterproof film, which we recommend for use on the glass for safety.

Please note that scratches show up easily on the black finish, so use care during the installation process.
