LD-309 Stainless Steel Glass Door Lock Cylinder Keyed Frameless | Wholesale Supplier

The LD-309 Stainless Steel Glass Door Lock with Cylinder is a secure, purpose-built locking solution designed for frameless glass doors in commercial, hospitality, and residential settings. The lock body is constructed from stainless steel to deliver dependable strength and corrosion resistance, while the keyed cylinder, available in brass or zinc alloy, provides positive, tamper-resistant access control. Supplied as a complete set, the LD-309 includes the lock body, cylinder, nickel silver keys, and a steel strike plate, giving installers everything required for a clean, professional fit on glass thicknesses from 8mm to 12mm. Rubber gaskets cushion the glass at every contact point to prevent stress, chipping, or movement during operation. Engineered specifically for frameless glass door applications, the LD-309 combines security with the clean, minimal aesthetic that designers expect from modern glass architecture. The keyed mechanism ensures that only authorized users can operate the door, making it well suited to office entries, retail storefronts, hotel bathrooms, and conference room partitions where controlled access or privacy is required. The precision-machined components align accurately during installation, reducing play and ensuring smooth key rotation and reliable latching over thousands of cycles. A choice of mirror polish, brushed satin, or matte black finishes allows the lock to coordinate seamlessly with adjacent glass hardware such as hinges, handles, and door closers. As a wholesale supplier of door lock hardware, we offer the LD-309 at competitive volume pricing with a minimum order quantity of 100 sets and production lead times of 15-25 days. OEM customization is available, including keyed-alike or keyed-different configurations, custom key profiles, bespoke finishes, and private-label branding to meet the procurement requirements of distributors, contractors, and project developers. Every lock set undergoes quality inspection to verify cylinder function, key cut accuracy, and finish consistency before shipment, and each unit is backed by CE and ISO 9001 certification.
