Sliding Glass Door Lock Indoor Knob & Outdoor Key Glass Door Lock

Left-Side Operating Unit: Features a polished chrome knob bearing a "SUS 304" marking, indicating it is constructed from 304 stainless steel. The knob serves as the interior control mechanism, allowing for direct manual rotation to lock or unlock the door; no key is required, facilitating quick and convenient passage for those inside.
Right-Side Locking Unit: Houses the corresponding bolt mechanism, featuring pre-drilled mounting holes and a bolt aperture. It functions in conjunction with the operating unit to secure the door. The base incorporates a glass-clamping mechanism, making it suitable for installation on frameless glass doors.
Installation Accessories:
Includes an Allen wrench, positioning pins, and mounting screws. These components are used to securely clamp the lock body onto the glass, enabling installation without the need for drilling—thereby eliminating the risk of glass breakage.

No-Drill Installation: Secured to the glass via a clamping mechanism, installation is completed simply by utilizing the included specialized fittings; this method preserves the structural integrity of the glass and is compatible with frameless glass doors ranging from 8mm to 12mm in thickness.
Single-Door Compatibility: Specifically designed for single-panel sliding glass doors, this lock enables the secure locking and immobilization of the door, effectively preventing it from being opened without authorization.
Durable and Rust-Resistant: Constructed from high-grade 304 stainless steel with a brushed surface finish, the unit offers exceptional resistance to impact, prying attempts, and corrosion—making it ideal for high-traffic environments such as retail shops, office buildings, and showrooms.
Convenient Operation: Featuring an interior-side knob control, the lock can be engaged or disengaged without the need for a key, thereby balancing robust security with efficient user access.
