Structural & Material Data
Housing & Cover Plates Lock housings are die-cast zinc or machined aluminum, providing internal structural rigidity. Outer cover plates utilize 1.2mm to 1.5mm stamped Stainless Steel 304 (standard) or SS316 (coastal/exterior applications).
Friction & Adhesion (No-Drill Models) Clamp-on models grip the glass using structural tightening screws driving against heavy-duty EPDM friction gaskets. This mechanism achieves an extraction resistance exceeding 1,200 Newtons, holding the lock dead-center without requiring glass cut-outs.
Cylinder & Deadbolt Solid brass lock cylinders operate a hardened steel deadbolt. The deadbolt throws 15mm to 18mm into the floor strike plate or matching glass keep, securing double-action or single-action frameless doors.
Application Guide: Cut-Out vs. No-Drill
Choose the lock body based on project timeline and glass fabrication stage:
Patch Fitting (Requires Glass Cut-Out): Fits into pre-tempered CNC cut-outs. Provides maximum physical security against lateral force. Ideal for exterior storefronts and main commercial entrances.
Clamp-On (No-Drill): Slips over the edge of the glass and tightens via hex screws. Eliminates the need for pre-fabrication glass processing. Suitable for interior office partitions, meeting rooms, and retrofitting existing doors.
Manufacturing & Quality Control
Factory operations focus on dimensional accuracy and finish consistency for wholesale distribution:
Machining: Internal lock components are processed on 4-axis CNC centers, maintaining +/-0.05 mm tolerances for smooth cylinder actuation.
Corrosion Testing: SS304 configurations undergo 48-hour Neutral Salt Spray (NSS) testing. SS316 configurations undergo 96-hour NSS testing to verify oxidation resistance.
Finish Calibration: Brushed and polished finishes undergo visual matching against standardized limit samples under 6500K lighting to eliminate batch-to-batch color variance.

Frequently Asked Questions
Q: What is the required door gap for center-mount glass-to-glass locks?
A: A minimum gap of 4mm to 6mm between the active and passive glass panels is required to accommodate the deadbolt clearance and prevent glass collision during swing.
Q: Do you supply the floor strike plates and dust-proof strikes?
A: Yes. Bottom-mount glass locks include a standard spring-loaded dust-proof strike plate (SS304) that prevents debris accumulation in the floor hole when the door is unlocked.
Q: Can the lock cylinder be swapped after installation?
A: On cut-out (patch) models, the cylinder is standard Euro-profile or mortise and can be swapped by removing the side setscrews. On low-profile clamp-on models, the cylinder is factory-integrated and requires replacing the entire inner housing.
Q: Will the clamp-on lock slip down the glass over time?
A: When torqued to the specified 12-15 Nm using the provided hex key, and used strictly on the specified glass thickness (e.g., exactly 12mm with the correct gasket), the lock maintains position without vertical slip under standard commercial usage.
