Frameless Glass Door Lock Thumbturn & Key Operated Glass Lock

The set includes two semi-circular lock bodies, both made of SUS304 stainless steel with a brushed finish, designed to fit frameless glass doors with a thickness of 10–15mm.

The left lock body features an inside thumbturn, while the right lock body has an outside key cylinder, enabling a dual-control mode: thumbturn operation from the interior and key operation from the exterior.

Black rubber gaskets are installed at the contact points between the lock bodies and the glass to protect the glass from direct stress and prevent damage during installation.

• 3 matching keys for the exterior lock cylinder.
• Mounting screws, expansion plugs, and an Allen wrench for installation.
• The lock adopts a drill-free design, eliminating the need for drilling holes in the glass. It is secured firmly by clamping force on the glass.

This lock is primarily designed for frameless double-opening glass doors (e.g., glass partition doors in retail stores, offices, and commercial buildings). It serves as an alternative to traditional floor locks, installed at the middle of the door panel without compromising the transparent and sleek appearance of the glass door.

The drill-free design eliminates the risk of glass cracking caused by drilling, while offering quick and easy installation. It also provides reliable anti-theft protection: users can unlock the door quickly via the thumbturn from the inside, while access from the outside requires a key.

• Safety & Durability with Premium Build Quality

  Crafted from high-grade SUS304 stainless steel with a brushed finish, this lock delivers exceptional corrosion resistance, rust-proof performance, and scratch resistance. It maintains stable appearance and performance even with long-term use, making it ideal for humid, windy outdoor storefront environments.

• Drill-Free Installation, Zero Glass Damage

  The lock body is secured via clamping force, eliminating the need for drilling holes in the glass. This fundamentally removes the risk of glass cracking or spontaneous breakage. Installation is quick and simple, requiring no specialized tools, while preserving the clean, transparent aesthetic of your glass door.

• Dual-Control Design for Maximum Convenience

  Features an interior thumbturn for one-touch unlocking, enabling quick exit in emergencies; the exterior key cylinder provides reliable anti-theft protection. It balances security and daily access efficiency, perfectly meeting the "separated indoor/outdoor access control" needs of offices and retail stores.

• Thoughtful Glass Protection Design

  Built-in rubber gaskets at the contact points between the lock and glass cushion pressure, prevent slippage and scratches during installation and use. This detail significantly reduces the risk of glass breakage, extending the service life of your glass door.
