Engineering Specification & Product Overview
Engineered for sliding pocket door systems in commercial, hospitality, and architectural millwork applications, these concealed lock assemblies provide flush integration, precise backset alignment, and reliable privacy or passage control. The mortise-installed hardware sits completely flush within the door edge and face, eliminating protrusion hazards while preserving smooth sliding clearances in solid-core and hollow-core door panels.

Metallurgy, Manufacturing & Quality Control
Long-term mechanical stability in architectural hardware requires strict metallurgical control and tight machining tolerances.
Material Composition: Base housings are gravity die-cast from high-purity zinc alloy (ZAMAK 3) or precision-machined from solid brass and SUS304 stainless steel, preventing structural deformation under lateral pulling loads.
Surface Treatment & Corrosion Resistance: Finished via automated electroplating and Physical Vapor Deposition (PVD). All batches undergo Neutral Salt Spray (NSS) testing exceeding 96 hours to prevent pitting or discoloration in humid environments such as hospitality bathrooms and coastal properties.
Machining Tolerances: Internal cam mechanisms and spring assemblies are CNC-machined to tolerances within +/- 0.02 mm, eliminating handle play, rattle, and latch misalignment.
Cycle Durability Testing: Internal latch and retraction mechanisms are tested to 200,000 operational cycles under standard load, compliant with ANSI/BHMA A156.14 grade performance benchmarks.
Application Environments & Project References
Hospitality Guest Rooms: Interconnecting bathroom and closet sliding doors requiring robust privacy mechanisms and quiet latch retraction. (Successfully supplied for a 450-room luxury hotel renovation project in North America.)
Commercial Office Suites: Boardrooms and executive offices utilizing high-density acoustic sliding panels. (Specified across multiple corporate headquarters for sound-dampening architectural millwork.)
High-End Residential Developments: Custom millwork projects requiring minimalist flush hardware matching contemporary interior design lines. (Trusted by premier custom home builders for high-end coastal properties.)
Supply Chain & OEM/ODM Capabilities
Production Capacity: 50,000 units monthly utilizing automated CNC milling lines, multi-axis die-casting machines, and dedicated assembly cells.
Packaging Standards: Individual components are packed in anti-corrosion VCI (Volatile Corrosion Inhibitor) film, partitioned in corrugated cartons, and palletized with edge protectors for international maritime and air freight.
Customization Support: Laser-etched private branding, custom box printing, and tailor-made faceplate sizing based on CAD/STEP drawings.
Technical FAQ & Procurement Considerations
Q: How is door edge chipping prevented during mortise installation?
A: Each lock ships with a laser-cut routing template. Faceplates and edge pulls feature pre-bored mounting screw holes with countersunk bevels to sit flush with wood grain without splitting or tear-out.
Q: What occurs if a locked pocket door requires emergency egress?
A: Privacy models (PDL-101-PRV) include an exterior emergency release slot, allowing actuation via a flat-head screwdriver or coin in compliance with life-safety building codes.
Q: How is batch-to-batch finish consistency maintained?
A: Spectrophotometer colorimeter readings are logged during every electroplating and PVD production run to maintain strict Delta E color variance limits across bulk shipments.
