Product Overview
The oval double cylinder is a brass profile cylinder in the Swiss and Oval Cylinders category, built for legacy and retrofit door hardware and stated in the manual as EN 1303 compliant. It uses a brass housing and brass plug, 6 active pins as standard, and a 30 mm A plus 30 mm B length that sets the 60 mm overall L dimension.
Buyers specifying an oval profile cylinder usually face a door that was cut for an oval fixing and cannot take a round DIN cylinder without reworking the lock case. This cylinder drops into that opening, keeps the existing cam and screw positions, and adds optional anti-drill protection in the housing and plug when the door is on an exposed elevation.
Key Features
- Oval profile body: fits doors already cut for an oval fixing, so the lock case does not need to be replaced.
- Brass housing and plug: both parts are machined from brass, which holds the pin chambers and cam seat in tolerance.
- 6 active pins standard: the pin count can be ordered at 5 or 7 to match the security level of the rest of the building.
- Vertical and dimple key types: the keyway can be specified to suit the key system already in use on site.
- Optional anti-drill protection: a hardened element in the housing and a second in the plug slow a drill attack on the cylinder face.
- Master key possibilities: KA, CE, MK and GMK systems can be quoted, so one key can serve a floor or a whole site.
- Five finishes: polished brass, satin nickel, polished chrome, matt chrome and raw brass cover most door hardware schedules.

Industrial Applications
- Oval double cylinder for retrofit door hardware: maintenance contractors replacing cylinders in older timber and steel doors use the oval body to avoid cutting the lock case, and specify the 30-80 mm A and B lengths to suit each door leaf.
- Oval double cylinder for legacy lock replacement: property managers keeping an existing oval lock case order the cylinder with the same key type and pin count, so the door keeps its original hardware and only the cylinder changes.
- Oval double cylinder for architectural door sets: specifiers writing a hardware schedule for a refurbishment list the brass oval cylinder for locks where the oval cutout is already in the door, with satin nickel or matt chrome to match the ironmongery finish.
- Oval double cylinder for master key systems: facility teams running KA, CE, MK or GMK suites order the cylinder keyed into the building master plan, so one key opens the doors on a floor and the site key opens the rest.
Key Advantages
The oval body removes the lock-case work from a cylinder swap. A contractor measuring a door does not have to quote for cutting a round hole in a steel case, and the door stays in service for the length of the change.
Brass in the housing and plug keeps the pin bores and cam seat stable over years of key operation, which matters on doors that cycle many times a day. The material list states brass for both parts, not a zinc body with a brass face.
Anti-drill protection is offered as two separate options, housing and plug. A buyer can put the protection on the external side of a door and leave the internal side standard, which keeps the cost where the risk is.
Master keying is quoted as KA, CE, MK or GMK, so the cylinder can be ordered into an existing key schedule instead of being re-keyed after delivery.
Lengths are ordered as A and B from 30-80 mm, so the cylinder is built to the door rather than cut down on site. The cam and fixing screw positions follow the oval lock case, which lets the existing hardware stay in place on a retrofit.
How to Choose the Right Configuration
| Standard 30/30 mm oval double cylinder | suits a door leaf that takes a 60 mm overall cylinder, the common case in retrofit work. |
|---|---|
| Extended A and B lengths (30-80 mm) | for thicker doors, deep escutcheons or doors where the cylinder has to sit flush with the furniture. |
| 5-pin version | for lower-traffic internal doors where the existing key system is 5-pin. |
| 7-pin version | for external or higher-security doors that need the extra pin tolerance. |
| Anti-drill housing and plug options | for doors on exposed elevations, rear access doors and ground-floor openings. |
| KA, CE, MK or GMK master keying | for sites that need one key to cover a group of doors or a whole building. |
Why Choose Us
We quote the oval double cylinder against the door schedule you send, including the A and B lengths and the key type, so the order arrives ready to fit. Ask for the oval double cylinder price with your quantities and lengths and we return a quotation with the configuration written out.
We machine the brass housing and plug in-house and assemble the pin stacks to the pin count on the order. OEM and ODM work is quoted from your drawing or sample, including key marking and finish.
Spare keys, fixing screws and replacement cylinders ship from the same production batch, which keeps a master key system consistent when a door is added later. We answer technical questions on pin counts, cam types and length combinations before the order, not after.
Every order carries a warranty on the cylinder against defects in material and workmanship; the term is stated on the quotation. After-sales support covers fault diagnosis and replacement of a faulty cylinder, and spare parts are available from the same batch as the original order. Technical support on pin counts, cam types and length combinations continues after delivery.
Factory Strength
Production covers machining of the brass housing and plug, pin stack assembly, cam fitting and key cutting, with the cylinder assembled and function-tested before packing. Each unit is checked for key operation, pin pick-up and cam movement on the bench, and the finish is inspected under light before it goes into the export carton. Export orders ship with the finish, length and keying marked on the carton, and the factory works to the EN 1303 reference stated in the product manual.
Quality Control
Incoming brass bar stock is checked for diameter and grade before machining. In-process checks cover pin bore diameter, cam seat depth and plug fit, and each assembled cylinder is operated with its key to confirm pin pick-up and return. Final inspection checks finish, key quantity and length marking against the order.

FAQ
What is an oval double cylinder and how does it differ from a round DIN cylinder?
It is a double cylinder with an oval profile body, which fits doors cut for an oval fixing rather than the round profile of a DIN cylinder. The cam and fixing screw positions follow the oval lock case, so the existing hardware can stay in place.
What do the A, B and L dimensions mean on this cylinder?
A is the length from the cam to one end of the cylinder and B is the length from the cam to the other end. L is the overall length, so the standard 30 mm A plus 30 mm B gives a 60 mm L. Order A and B from 30-80 mm to suit the door.
Can I order a 7-pin version instead of the standard 6-pin?
Yes. The cylinder is built with 6 active and 6 passive pins as standard, and 5 or 7 pins can be specified on the order. Tell us the pin count of the existing key system and we match it.
Can the oval double cylinder be used for retrofit door hardware on older doors?
That is the main use. The oval body drops into an existing oval cutout, so a maintenance contractor can replace the cylinder without cutting the lock case. Measure the door thickness and the existing cylinder lengths before ordering.
Can these cylinders be supplied as part of a master key system?
Yes. KA, CE, MK and GMK possibilities are stated for this cylinder. Send the key schedule for the building and we quote the cylinder keyed to it, including the key quantity per cylinder.
What is the oval double cylinder price and how do I get a quotation?
Price depends on the A and B lengths, pin count, key type, anti-drill options and finish. Send the quantities and the door schedule and we return a written quotation with the configuration listed.
What is your MOQ for a trial order?
MOQ is set against the configuration, since length, keying and finish change the production run. Tell us the trial quantity you need and we confirm the minimum for that specification.
Do you offer OEM marking and can you supply an oval double cylinder datasheet?
OEM and ODM work is quoted from your drawing or sample, including key marking and finish. A datasheet covering the specifications on this page can be issued with the quotation.
What are the payment terms and lead time?
Payment terms and lead time are confirmed on the quotation, as both depend on order quantity and the keying work involved. A deposit is normally required before production starts, and the balance terms are agreed at order confirmation.
