Heavy-Duty SUS 304 Stainless Steel Glass Door Lock Interior Hidden Deadbolt Door Lock

Dual-Component Design
Lock Body 1: The exterior/key-operated component features pre-drilled holes for installing the lock cylinder and mounting screws, allowing for external unlocking and locking via a key.
Lock Body 2: The interior/knob-operated component features a polished metal knob at the top, enabling direct manual locking from the inside without the need for a key—balancing both security and convenience.
Materials and Craftsmanship
The main body is constructed from SUS 304 stainless steel, offering excellent rust and corrosion resistance. The knob features a polished chrome finish, combining both premium aesthetics and exceptional durability.
Installation and Compatibility
The base utilizes a glass-clamping mechanism; combined with side-mounted fixing screws, it allows for direct, drill-free installation on frameless glass doors (compatible with common glass thicknesses of 8–12 mm), thereby eliminating the risk of glass breakage associated with drilling.
Pre-drilled screw holes are provided for securely mounting the lock cylinder, knob, and the entire lock assembly, ensuring a robust and stable structure.

No-Drill Installation: Secured to the glass via a clamping mechanism, requiring no drilling; this ensures convenient installation without compromising the structural integrity of the glass.
Dual Operation Modes: Features key control on the exterior and a rotary knob on the interior, thereby ensuring security against theft in public areas while facilitating quick and easy passage for occupants inside.
Exceptional Durability: Constructed from 304 stainless steel, offering robust resistance against impact, prying, and rust—making it ideal for high-traffic environments such as retail shops, office buildings, and showrooms.
Broad Compatibility: Primarily designed for single-panel frameless glass sliding doors, but can also be paired for use with double-opening glass doors.
