Australian and Scandinavian oval cylinders serve different lock interfaces and should be ordered as separate formats. TOPTEK’s Australian oval drawing shows a 20 × 35 mm front profile, while its Scandinavian oval drawing shows 18 × 31.5 mm. The products also use different key-profile references and rear operating arrangements. Choose the format that matches the lock case, fixing hardware and trim, then specify length and keying. The shared word “oval” does not make them interchangeable.
For importers: keep the format, lock model and rear interface in the stock description. A front photograph alone is not enough to distinguish a complete replacement specification.
Compare the TOPTEK options side by side
| Purchase detail | Australian oval | Scandinavian oval |
|---|---|---|
| TOPTEK product reference | AOC01 | SOC01 |
| Front profile in TOPTEK drawing | 20 mm wide × 35 mm high | 18 mm wide × 31.5 mm high |
| Standard key-profile reference | C4 | TV-3D |
| Selection emphasis | Lock-compatible cam and retaining arrangement | Module-series interface, inside/outside arrangement and associated hardware |
| Length | Specify dimension L for the assembly | Specify dimension L for the assembly |
These dimensions describe the illustrated TOPTEK products, not every manufacturer’s oval cylinder. Neither front-profile dimensions nor the regional name specifies the cylinder’s length. The door, trim and operating interface determine which length is required.
Australian oval: order the cam with the cylinder
The TOPTEK AOC01 Australian oval cylinder uses the C4 key-profile reference, with a restricted keyway option. The Australian oval range lists satin nickel, satin chrome and black finish options, and a supply arrangement with four common cams. Name the required cam or provide the lock sample so the quoted package can identify the correct operating parts.
A cylinder can enter an opening without operating the lock correctly. The rear cam must engage the mechanism in the right position and complete the required movement. This is why an importer should record the lock model and cam reference alongside cylinder dimensions, rather than stocking every Australian oval as one interchangeable item.
Construction keying and master key systems are available on request. State the project keying requirement when requesting a quotation so it can be coordinated with the chosen profile, length and lock function.
The TOPTEK SOC01 Scandinavian oval cylinder is offered for module-series applications with the TV-3D key-profile reference. Protected key-profile and security-card options are available. Define the required key-control arrangement and replacement-key supply as part of the commercial specification.
Record what is fitted on the outside and inside of the door: cylinder, turn or other specified component. Include the rings, sleeves and fastening arrangement used by the selected lock and trim. The buyer needs a complete bill of materials, not only the visible cylinder body.
For a replacement enquiry, photograph the removed cylinder from the front, rear and side and include the lock case reference. This helps distinguish the operating connection from the similar-looking front profile before samples or stock are ordered.
One project key plan does not mean one cylinder body
TOPTEK supports master key hierarchies with up to five management levels. For distributors and project owners, this allows a discussion of individual, departmental and wider facility access within a coordinated system. The hierarchy describes opening permissions; it does not change the physical interface required by each door.
When a project mixes regional formats, confirm compatible key profiles and the proposed system design before promising one common key. C4 and TV-3D references should not be treated as the same keyway. Use the commercial cylinder keying schedule to record door permissions separately from body format and quantities.
Factory assembly to the agreed key chart and component supply for local assembly are two TOPTEK supply routes. A door manufacturer may prefer cylinders prepared for its door schedule; a locksmith distributor may need components for local configuration and service. Include the preferred route so the quotation reflects the work to be performed locally.
Make the first sample answer the replacement question
Fit the selected cylinder with the intended lock, trim and retaining hardware. Check seating, retention, key insertion and withdrawal, and the complete locking movement from the required sides. A loose cylinder turning smoothly on a desk does not show that its cam or connector will operate the project lock.
TOPTEK’s production quality controls include first article and in-process inspections. Connect the agreed sample to the drawing revision, length, keying and finish on the purchase order. This gives repeat orders a clear reference and helps prevent substitution between visually similar oval formats.
What to include in an oval cylinder RFQ
- Target market, lock case and trim model, with photographs or a reference sample.
- AOC01 or SOC01 format, front profile, required length and rear interface.
- Inside/outside arrangement, retaining screws, rings and other supplied components.
- Key profile, key quantities and individual, keyed-alike or master-key requirements.
- Factory assembly or local component supply, finish, marking and packing.
- Quantities by configuration and the project-specific documents required for the exact model.
TOPTEK’s construction cylinder range gives procurement teams access to several regional formats through one manufacturing discussion. Keep separate order lines for different interfaces while coordinating packaging, keying and delivery requirements across the project.
Frequently asked questions
No universal interchangeability should be assumed. Match the profile, length, fixing and rear operating interface to the exact lock and trim.
What dimensions distinguish the illustrated TOPTEK oval formats?
The Australian oval drawing shows a 20 × 35 mm front profile; the Scandinavian oval drawing shows 18 × 31.5 mm. Specify cylinder length separately for the assembly.
Can both formats be included in one master key project?
They can be considered in a coordinated project design where key profiles and system capacity are compatible. Shared permissions do not make different cylinder bodies physically interchangeable.
What does TOPTEK’s five-level capability mean?
It means support for up to five levels of master key management hierarchy. It is an access-permission capability, not a cylinder security grade.
Request the right oval cylinder package
Start with the lock interface, then select the cylinder and keying arrangement. Send TOPTEK the lock reference and cylinder measurements to discuss a matching sample. Add quantities, supply route and private-label requirements for a formal quotation covering the complete package. TOPTEK’s commercial lock manufacturing programme supports the wider OEM discussion.
