Product Selection Guide
Verify these configuration parameters prior to project submittal or bulk ordering to ensure exact site compatibility:
Glass Edge Preparation & Cutout: Specify whether the glass requires custom notch fabrication or if the lock installs within an aluminum/stainless steel perimeter door stile. Factory-certified CAD shop drawings are available upon request.
Backset Measurement: Measure the distance from the outer edge of the glass door stile to the centerline of the cylinder hole. Available standard backsets are 50 mm, 55 mm, and 60 mm.
Cylinder Configuration & Keying:
• Thumbturn & Cylinder: Configured for conference rooms and executive office partitions.
• Double Cylinder: Applied where secure key control is required on both sides of the glass panel.
• Keying Options: Supplied in Keyed Alike (KA), Keyed Different (KD), or Master Keyed (MK) systems.
Door Handing: Select Left Hand, Right Hand, or Universal Reversible Latch according to swing direction and egress requirements.

Manufacturing Metallurgy, Machining & Quality Control
Material Properties & Components
• Enclosure: Fabricated from 1.5 mm cold-rolled SUS304 stainless steel sheet, resisting mechanical binding caused by door frame deflection under load.
• Internal Cams and Gears: Investment-cast solid brass, machined to tolerances within +/-0.03 mm to eliminate rotational play in the cylinder interface.
Production Machining & Assembly
• CNC Machining Centers: Housing pockets and faceplate fastener holes are milled using 4-axis vertical CNC centers to ensure uniform hole spacing.
• Automated Pneumatic Assembly: Internal springs, latches, and deadbolts are assembled and torque-verified on automated jig lines to maintain consistent operational resistance.
Testing & Compliance Protocols
• Salt Spray Corrosion Testing: Finishes undergo a 96-hour neutral salt spray test (ASTM B117) to verify resistance to pitting or rust in high-humidity or coastal environments.
• Cycle Endurance Testing: Randomly sampled units undergo mechanical actuation exceeding 200,000 continuous cycles on pneumatic test rigs.
• Optical Comparator Inspection: 100% verification of keyway alignment, backset depth, and faceplate squareness prior to packaging.
Commercial & Supply Chain Terms
Minimum Order Quantity (MOQ): 100 sets per finish/specification; pilot sample orders accepted for project approvals.

Frequently Asked Questions
Q: Can this mortise lock be mounted directly to frameless glass without an aluminum stile?
A: Yes, provided the tempered glass panel is pre-cut according to our factory-certified CAD template to accommodate the lock case and patch fittings or clamping rail stiles. Nylon or rubber gasket shims must be used between the lock body clamp and the glass surface to distribute clamping pressure evenly and prevent edge stress fractures.
Q: What standards do the euro-profile cylinders meet?
A: The supplied euro cylinders comply with EN 1303 mechanical durability and key security standards, incorporating anti-pick mushroom driver pins and hardened steel drill-resistance inserts within the cylinder body.
Q: Are replacement components available separately for facility maintenance contracts?
A: Yes. Interchangeable euro cylinders, faceplates, and strike plates are supplied as standalone aftermarket parts to support commercial building maintenance and master-key system expansions.
Q: How is finish consistency controlled across multi-phase commercial shipments?
A: All stainless steel components undergo batch-processed mechanical brushing (for Satin Stainless Steel) with profilometer surface roughness verification (Ra <= 0.4 um) to maintain uniform light reflection across separate production lots.
