Core Configurations & Applications
Hardware Specifications
- Precision Zinc Alloy Housing: Manufactured from die-cast zinc alloy to European DIN dimensional standards (32.8 x 16.8 x 9.8 mm), ensuring precise fitment into standard European mortise lockcases while providing a cost-effective hardware solution.
- Brass Pinning Architecture: Features solid brass pin tumblers (configured with 5 or 6 pins per side) to provide smooth key engagement and mechanical durability, paired with either a zinc alloy plug or an upgraded solid brass plug.
- Symmetrical & Asymmetrical Sizing: Standard 60 mm overall length (30/30 mm symmetrical split), with A and B barrel dimensions individually scalable from 30 mm to 60 mm to match various door panel thicknesses and escutcheon depths.
- Dual Key Platform Compatibility: Accommodates traditional vertical edge-cut keys or modern flat dimple keys. Key bows are available in H4 (asymmetric flared), H7 (square with rounded corners), or customized OEM profiles.
- Sintered Steel Cam: Driven by a wear-resistant sintered steel cam (powder metallurgy) designed for reliable latch and deadbolt actuation, secured via an M5 fixing screw (adjustable lengths from 40 mm to 80 mm).
Primary Application Environments
- Residential Doors: Suitable for interior timber doors, apartment entry doors, and light-duty exterior entrances balancing budget constraints with functional security.
- Door Manufacturing & Assembly Facilities: Ideal for pre-hung door factories and fabricators requiring standardized Euro profile hardware with reliable batch consistency.
- Volume Commercial Hardware Supply: Designed for hardware wholesalers and distributors serving high-volume residential developments and renovation projects.
Optional Configurations & Customization
Modular Component & Material Selections
Based on specific project specifications, the following options can be customized:
- Plug Material: Standard zinc alloy for competitive pricing, or solid brass for enhanced cycle durability.
- Pin Count: 5-pin setup for standard lock programs, or 6-pin setup for higher combination capacity.
- Key Customization: Supplied with 3 keys standard; optional brass key materials and custom-stamped OEM key heads (H4, H7).
- Dimensional Offsets: Configurable overall lengths ranging from 60 mm (30/30 mm) up to 120 mm (60/60 mm), including asymmetrical offsets (e.g., 30/40 mm, 35/45 mm, 40/50 mm).
- Architectural Surface Finishes: Electroplated and coated finishes available in Satin Nickel, Polished Chrome, Matt Chrome, Gold, Matt Black, and Antique Brass to coordinate with exterior and interior door handles.

Frequently Asked Questions
The housing is die-cast zinc alloy for both options. Selecting a solid brass plug provides higher internal wear resistance and tighter operational tolerances for higher-traffic doors, while the zinc alloy plug offers an economical solution for standard residential doors.
Yes. Both sides can be independently configured between 30 mm and 60 mm (e.g., 30/40 mm, 35/45 mm, 30/50 mm) to match off-center mortise lockcases and varying exterior door panel thicknesses.
The cylinder can be supplied in six surface treatments: Satin Nickel, Polished Chrome, Matt Chrome, Gold, Matt Black, and Antique Brass to match diverse architectural door handle suites.
