Product Overview
The Euro Profile Half Cylinder is a brass half euro cylinder for locks that need a cylinder on one side only, built to the DIN EN 1303 half cylinder standard and supplied in a compact 10 mm B-dimension. It is a single-side cylinder for door locks, cabinet locks, padlocks, shutter locks and access-control hardware, used by lock assemblers, door manufacturers, distributors and maintenance buyers. The body and plug are brass, the standard length is 40 mm overall with a 30 mm A-dimension, and the plug carries 6 active and 6 passive pins.
The short B-dimension is the reason buyers pick this model. Where a full double cylinder will not fit, or where the inside of the door must stay free of a key, the half cylinder gives a keyed outside face without the extra body length. Lengths from 30 mm to 80 mm, five finishes and KA, CE, MK and GMK keying let one part number cover a range of door schedules.
Key Features
- 10 mm B-dimension: the short body fits doors and cabinets where a double cylinder will not seat, so the outside stays keyed and the inside stays clear.
- Brass housing and brass plug: both wear surfaces are the same alloy, which keeps key turn consistent over repeated cycles.
- 6 active and 6 passive pins as standard, with 4-7 available: pin count can be matched to the keying level the job needs.
- Vertical and dimple key types: one cylinder family covers both key profiles, so a mixed project can be keyed from one supply.
- M5 x 55 fixing screw as standard, 40-80 mm optional: the screw length follows the door thickness without a second order line.
- Optional anti-drill protection in the housing and in the plug: two separate hardening points can be specified for higher-security doors.
- Anti-picking and anti-bumping protection available on request: the plug can be built to resist the two common entry methods.

Industrial Applications
- Half euro cylinder for door locks: door manufacturers and locksmiths fit it to timber, steel and aluminium doors where only the outside face is keyed. The 10 mm B-dimension clears shallow lock cases that will not take a double cylinder, avoiding a lock-case change or spacer on retrofit work.
- Half euro cylinder for cabinet locks: workshop and office furniture builders use the short body in steel cabinets and lockers. The 30-80 mm A-dimension is selected to match panel thickness, so the plug sits flush and the key turns without binding on the panel edge.
- Half euro cylinder for padlocks: padlock assemblers fit the half cylinder as the keyed core, with the optional anti-drill plug for outdoor and site use, where the plug resists drilling attack on the exposed keyway.
- Half euro cylinder for shutter locks: roller-shutter and grille installers specify the cylinder for the outside key point, with anti-picking and anti-bumping options on exposed shopfronts where the keyway is reachable from the street.
- Half euro cylinder for access control: integrators pair the keyed half cylinder with an electronic handle or strike, keeping a mechanical override on one side of the door so the opening still works during a power failure or reader fault.
Key Advantages
- The 10 mm B-dimension removes the fit problem that stops a double cylinder going into a shallow door or cabinet, so the buyer avoids a second lock case or a spacer.
- Brass in the housing, plug and key means the wear path is one alloy throughout; that is what keeps turn quality stable across a long door schedule rather than a single sample.
- Pin count, keying and security options are specified on one part number, so a project with mixed security levels can be sourced from one cylinder family instead of several.
- DIN EN 1303 compliance gives the specifier a recognised standard to write into the door schedule, and the five finishes let the cylinder match the ironmongery without a separate finish order.
- The half-cylinder format keeps the inside face free for a thumbturn, handle or electronic strike, so one door can carry a keyed exterior and a code-compliant escape or access side without a second lock case.
How to Choose the Right Configuration
| Standard 40 mm L / 30 mm A half cylinder | suits standard timber and steel doors where the lock case takes a 10 mm B-dimension and no special keying is needed. |
|---|---|
| Extended A-dimension 30-80 mm | for thicker doors, cabinets and shutters; measure the door thickness and the lock case depth before ordering. |
| KA keyed-alike | for a building or furniture run where one key should open every cylinder. |
| MK / GMK keying | for sites with a master-key hierarchy, from a single door up to a multi-level schedule. |
| Anti-drill plus anti-picking and anti-bumping | for external doors, shutters and padlocks where forced or covert entry is a real risk. |
| Satin nickel or chrome finish | where the cylinder must match lever handles and escutcheons in a visible location. |
Why Choose Us
We quote the euro profile half cylinder price against your length, finish and keying, so the figure you receive matches the part you will fit, not a base model.
We build the cylinder in brass and can hold a keying schedule across repeat orders, which matters when a project runs in phases.
China-based buyers work with us directly: we handle OEM marks, keying and packing to your instruction and confirm each detail in writing before production.
Spare keys and replacement cylinders are quoted from the same keying records, so a later order opens the doors the first one did. Technical support on pin count, B-dimension and finish selection is available before you specify, and we answer fitting and keying questions after delivery.
Factory Strength
Production runs in-house from brass component machining through plug assembly, pin loading, keying and finish. Each cylinder is built to the DIN EN 1303 drawing, then checked for key turn, pin engagement and finish before packing. Keying is recorded against the order so repeat batches can be matched. We supply lock assemblers, door manufacturers and distributors in export markets, and handle OEM marks and packing to the buyer’s instruction.
Quality Control
Incoming brass stock is checked before machining. In-process checks follow the plug and housing through pin loading and keying, and every cylinder gets a final key-turn and function check before it is packed. Keying is verified against the order record, and the finish is inspected under light for the specified option.
- Incoming brass material inspection
- In-process pin and keying checks
- Final key-turn and function test per cylinder
- Keying record kept against the order for traceability
Packaging & Delivery
Cylinders are packed individually and boxed in cartons for export, with keys and fixing screws included as specified.

FAQ
What is the B-dimension on this half cylinder and why does it matter?
The B-dimension is the body length from the cam face to the end of the cylinder, and on this model it is 10 mm. A short B-dimension lets the cylinder sit in shallow lock cases where a longer body would not fit.
Can I get the euro profile half cylinder specifications as a datasheet?
Yes. The specification list on this page covers the standard build, and we can send a datasheet with the exact length, finish and keying you are considering.
Which keying options are available?
KA, CE, MK and GMK are available. Send the keying schedule and we will confirm what can be held across the order.
Can the half euro cylinder be used for cabinet locks and padlocks?
Yes. The 30-80 mm A-dimension covers cabinet panel thicknesses, and the same cylinder is used as the keyed core in padlocks. Tell us the panel or body thickness when ordering.
Do you offer anti-drill and anti-bumping protection?
Anti-drill protection in the housing and in the plug is optional, and anti-picking and anti-bumping protection are available on request. Specify which doors need them.
What is the euro profile half cylinder price for a trial order?
Price depends on length, finish, keying and quantity. Send the configuration and quantity and we will quote; a trial order can be arranged.
What is your MOQ and lead time?
MOQ and lead time are set per order because keying and finish change the production run. We confirm both on the quotation before you commit.
Can you supply the cylinder with our brand and packing?
Yes. OEM marks and packing to your instruction are handled, with the artwork and packing details confirmed before production starts.
How is the cylinder packed for export?
Each cylinder is packed individually with its keys and fixing screw, then boxed in export cartons marked by length, finish and keying. Shipping terms are confirmed on the quotation.
