Core Material: The outer shell is made of 304 stainless steel with a brushed finish, making it rust-proof and corrosion-resistant, suitable for humid or outdoor environments, and resistant to rust even after long-term use.

Lock Body Structure: The square lock body design features four bolts. When locked, all four metal bolts extend simultaneously and insert into the matching mounting base, significantly enhancing anti-pry capabilities and providing higher security than ordinary single-bolt locks.

Lock Cylinder and Keys: The lock cylinder is key-controlled and comes standard with two keys. Turning the keys controls the extension and retraction of the bolts, enabling the lock to open and close.

Installation Features: Primarily designed for drill-free installation. No holes need to be drilled in the glass; it can be clamped onto the glass using a special fastener. It is compatible with 10-12mm thick tempered glass, offering convenient installation without damaging the door.

Applicable Scenarios: Mainly used for frameless glass sliding doors, double-leaf glass doors in shops, and office partition glass doors. It can also be used for anti-theft locking of single-leaf glass doors.

• Enhanced Security: The four-bolt design offers superior anti-theft performance compared to ordinary single/double-bolt locks, providing better resistance to prying and external force damage, making it suitable for high-security environments such as shops.

  High Durability: Constructed from 304 stainless steel, it is corrosion-resistant and wear-resistant, suitable for commercial glass doors that are frequently opened and closed, ensuring a long service life.

  Installation-Friendly: The drill-free design eliminates the need to damage the glass during installation, reducing the risk of glass cracking and making future disassembly and maintenance easier.
