Our range of construction cylinders is selected to work seamlessly with popular Australian lock bodies and architectural door hardware.

What Are Construction Cylinders?

Construction cylinders are temporary or semi-permanent lock cylinders used during the building phase. They allow builders, trades and site managers to secure doors and control access before the final keying system is installed. When it is time for handover, the construction cylinder can typically be replaced or converted so the permanent master key system or final cylinder can be fitted without changing the entire lock.

This staged approach helps protect valuable tools, materials and completed work while giving you the flexibility to update keying as your project progresses. For modern developments using premium architectural door hardware in matte black, stainless steel or brass finishes, construction cylinders are an essential part of the overall door and security plan.

Why Use Construction Cylinders on Your Project?

Secure Your Site Early

From the moment external doors and frames are installed, construction cylinders help you lock up quickly and easily. Instead of leaving front door and external openings unsecured, you can fit a construction cylinder and immediately start managing site access. This is especially important on busy construction sites in Brisbane, regional Queensland and metro areas across New South Wales, where multiple trades may be coming and going at different times.

Simplify Key Control During Construction

Construction cylinders are designed to work with simple, practical keying arrangements during the build. You can issue construction keys to supervisors and trades, knowing that the final occupant keys will be completely separate. This helps reduce the risk of unauthorised access once the project is complete and makes it easier to manage lost or misplaced keys while work is still in progress.

Protect Your Investment in Premium Hardware

When you specify premium brands such as Barben, Dormakaba, Lockwood or Zanda for your architectural door hardware, construction cylinders help protect that investment. Rather than installing the final cylinders too early and exposing them to paint, dust and heavy use, you can run construction cylinders through the messy stages and then switch to clean, final cylinders closer to completion. This approach helps your modern, contemporary door hardware look and perform at its best from day one.

Construction Cylinders for Residential and Commercial Projects

Multi-Residential and Apartment Developments

For multi-residential and apartment projects, construction cylinders are almost essential. They allow you to control access to individual units, common areas and plant rooms while trades are still on site, then transition smoothly to a permanent master key system at handover. This staged approach suits builders working across Australia-wide portfolios where consistency, security and efficiency are critical.

Commercial and Industrial Buildings

In commercial and industrial environments, construction cylinders provide a practical temporary locking solution for front doors, fire doors, internal offices and service areas. Site managers can provide access to key contractors without compromising the final key hierarchy. When the time comes, the cylinders can be swapped out for your chosen Dormakaba, Lockwood, Barben or Zanda cylinders to integrate with the building’s long-term access control plan.

New Home Builds and Renovations

For new homes and high-end renovations across Brisbane, coastal Queensland or New South Wales, construction cylinders make it easy to secure the property while work is underway. Builders can lock up at the end of the day using a simple construction key, then upgrade to the homeowner’s final keying once the project is nearing completion. This is especially useful on modern homes featuring premium front door hardware in matte black, stainless steel or brushed brass finishes, where you want everything to look pristine at handover.

Choosing the Right Construction Cylinder

Compatibility with Your Lock Bodies

When selecting a construction cylinder, the first consideration is compatibility with your lock bodies and door hardware. John Barnes Group stocks options suited to common Australian mortice locks, deadbolts and entrance sets used in both residential and commercial builds. Matching the cylinder to Lockwood, Dormakaba, Barben or Zanda hardware helps ensure a smooth installation on front doors, internal doors and external access points.

Function and Keying Requirements

Think about how the doors will be used during construction. Do you need a simple keyed entrance for external doors, or more complex arrangements for plant rooms, lift lobbies or restricted areas? Construction cylinders can be configured to suit different keying needs, from basic key-alike groups through to systems that anticipate a future master key setup. This ensures that what you buy online now will support the long-term security plan for the building.

Finish and Durability

Although construction cylinders are often temporary, durability still matters. Cylinders used on external doors or high-traffic entries must cope with weather, dust and heavy use. Where aesthetics matter during display stages or partial occupation, you can also choose finishes that complement your architectural door hardware, including stainless steel, matte black and brass-look options on compatible products.

Buying Construction Cylinders Online with John Barnes Group

You tap into a team that understands the realities of the building industry across Brisbane, regional Queensland, New South Wales and the rest of Australia.

Ordering online streamlines procurement for builders, locksmiths, facility managers and project managers. You can review specifications, plan your keying requirements and align your construction cylinder choices with the final hardware schedule, all before the first door is hung. This helps reduce delays, minimise rework and keep your project moving smoothly through each stage.

Installation and Handover Considerations

Installation of construction cylinders should be carried out by a competent installer or licensed locksmith, following the lock manufacturer’s instructions. Correct installation helps ensure the cylinder operates smoothly, maintains security and is easy to replace when it is time to move to the final keying system.

At the handover stage, you can schedule a managed changeover from construction cylinders to final cylinders keyed to the building’s long-term system. This changeover point is also a good opportunity to audit keys, confirm access levels and ensure that only the right people retain control of the final keys. John Barnes Group can support you with product guidance so that your construction and final cylinders work together as part of a cohesive, secure solution.

Frequently Asked Questions

What is a construction cylinder used for?

A construction cylinder is used to secure doors during the building phase, before the final keying system is installed. It allows builders and trades to lock up front doors, external entries and internal areas while work is still underway, then be replaced or converted to the permanent cylinder when the project is ready for handover.

Can I reuse a construction cylinder after the project is finished?

In many cases, construction cylinders are treated as temporary components and are swapped out for final cylinders at completion. Some systems are designed so the construction function is disabled once a final key is used, while others require the entire cylinder to be replaced. The best option depends on the hardware brand and system design, so it is important to plan this with your hardware and keying schedule.

Are construction cylinders suitable for both residential and commercial projects?

Yes. Construction cylinders are widely used on residential builds, multi-residential developments, commercial offices, industrial facilities and public buildings. They are particularly useful anywhere you need to manage access for trades and staff during construction, then transition to a secure, long-term keying system afterward.

Do construction cylinders work with brands like Barben, Dormakaba, Lockwood and Zanda?

Construction cylinders are available to suit many popular Australian hardware brands. At John Barnes Group, we offer options compatible with leading ranges from Barben, Dormakaba, Lockwood and Zanda, making it easier to align your construction cylinders with the final architectural door hardware you have specified.

Where specific standards or performance requirements apply, always review the product information and consult with your locksmith or security consultant to ensure the chosen cylinder meets the needs of your project.

When should I switch from construction cylinders to final cylinders?

The changeover usually happens close to practical completion, once major trades have finished and the risk of damage or uncontrolled access is lower. At this stage, the construction cylinders are removed or converted, and the final cylinders keyed to the long-term system are installed ready for occupancy.

Who should install construction cylinders?

Construction cylinders should be installed by a competent installer or licensed locksmith who understands the lock and hardware system being used. Correct installation ensures smooth operation, reduces the risk of lock issues during construction and makes the final changeover easier.
