Euro Half Cylinder

The Euro Half Cylinder is a practical locking solution widely used in commercial access control systems, cabinets, and partial door locking applications. This 3 keys solid brass half cylinder door lock cylinder, available in sizes from 40mm to 55mm, offers reliable mechanical performance with a compact structure that fits single-sided locking requirements. Manufactured with a high-quality solid brass body and plug, it ensures stable operation under frequent use and maintains consistent durability in long-term supply programs. With compliance to BS EN1303 standards and fire resistance tested up to 183 minutes under EN1634, this cylinder supports demanding project specifications in both residential and commercial environments. Its corrosion resistance reaches 96 hours under EN1670 testing, ensuring performance stability even in humid or coastal conditions.

1. Three Verified Standards

The DDLC010 Euro Half Cylinder complies with BS EN 1303, has completed a 183-minute fire test to EN 1634, and achieves 96-hour corrosion resistance under EN 1670. These documented results cover cylinder performance, fire testing, and finish resistance, helping consultants, door manufacturers, and project buyers review hardware schedules, prepare technical submittals, and complete inspections.

2. Six- or Ten-Pin Layout

The standard configuration uses six brass pins, while a high-security version offers ten pins arranged in two rows. Other sizes are also available. The ten-pin layout increases the number and arrangement of pin positions, expanding keying possibilities. Buyers can select the Euro Half Cylinder according to room classification, access requirements, and project budget.

3. Hierarchical Key Management

The Euro Half Cylinder supports master key, grand master key, construction key, and keyed-alike functions for access planning by building, floor, department, or room. Dimple and regular keys are available in 2.2mm-thick brass, with three-key or five-key configurations. Hierarchical keying helps facility teams control multiple openings while reducing the number of keys carried by authorized personnel.

4. 30-Degree Offset Cam

DDLC010 can use a 0-degree cam or a 30-degree offset cam that inhibits knock-through attacks and adds mechanical protection against impact. The cylinder body and plug are machined from solid brass to support precise alignment between the pin chambers, keyway, and cam transmission. This makes the Euro Half Cylinder suitable for door areas requiring enhanced mechanical protection.

5. Flexible Screw and Finishes

Standard accessories include three regular keys and one 65mm fastening screw, while other screw lengths can be supplied for different lock backsets. Finish choices include satin nickel, antique brass, antique copper, polished brass, chrome plate, PVD, and matte black. These configurations help the Euro Half Cylinder coordinate with lock trims, handles, door colors, and varied installation depths.

1. Office Buildings

Building entrances, private offices, and archive rooms can use the Euro Half Cylinder to create layered access permissions. Master and grand master key functions allow authorized personnel to open doors by floor or department, while keyed-alike arrangements serve multiple rooms with one key. Six-pin and ten-pin versions can be assigned according to each area’s security level.

2. Hotel Service Areas

Hotel offices, warehouses, equipment rooms, and staff areas require access permissions based on job roles. DDLC010 can use a construction key during project work before changing to the formal keying plan. The Euro Half Cylinder has passed a 183-minute EN 1634 fire test, while seven finishes support coordinated hardware specifications across different hotel zones.

3. Apartment Common Areas

Equipment rooms, property offices, shared storage areas, and service passages can use the Euro Half Cylinder. A master key arrangement helps property teams manage multiple openings with fewer keys, while the ten-pin double-row version serves rooms requiring tighter access control. The 30-degree offset cam also inhibits knock-through attacks at exposed common-area doors.

4. Retail Store Entrances

Retail stores, showrooms, and commercial service spaces can use DDLC010 to manage sales areas, offices, and stockrooms. Buyers can select dimple or regular keys and specify three or five brass keys according to staff requirements. The Euro Half Cylinder also supports different fastening-screw lengths for mortise locks with varied backsets.
