ADI Door Hardware & Security Locks

Secure your doors with confidence using ADI door hardware from John Barnes Group. This curated range of ADI locking bolts, surface locks, lock boxes and security accessories is ideal for front doors, external access points, internal service rooms and commercial applications across Brisbane, Queensland, New South Wales and Australia-wide. Whether you’re upgrading a single entry door at home or specifying architectural door hardware for a large project, you can buy ADI locks and bolts online and have them delivered directly to site.

ADI is trusted for robust, reliable security solutions that integrate seamlessly with modern and contemporary door hardware. From heavy-duty locking bars for solid core doors to compact security bolts for sliding doors and gates, our selection is designed to support both residential and commercial security requirements while maintaining a clean, professional look.

 

Heavy-Duty Security for Front & External Doors

External doors are your first line of defence, so choosing the right locking solution is critical. ADI lock bolts, surface-mounted bolts and high-security locks provide a strong mechanical barrier for front doors, back doors, side entries and external storerooms. Many options are suitable for solid core doors and are designed to resist forced entry attempts when correctly installed as part of a broader security system.

When you buy ADI door hardware online from John Barnes Group, you can select from a variety of finishes that complement contemporary and traditional exteriors alike, including popular options such as satin chrome, stainless-steel-look and other neutral tones that sit well alongside matte black and brass door furniture. These products are ideal for homes, units, small businesses and facilities that need dependable, low-maintenance security at key access points.

For doors that require an extra layer of protection beyond a standard latch or deadbolt, ADI locking bolts and surface locks can be used as secondary locking devices. This makes them particularly suitable for external doors opening to laneways, carparks, courtyards and service areas where additional reinforcement is recommended.

 

Secure Internal Doors, Storerooms & Plant Rooms

Security isn’t only about the front door. Internal doors often protect high-value or sensitive areas such as storerooms, server rooms, plant rooms, cleaners’ rooms and utility cupboards. ADI lock boxes, key-in-knob lock housings and locking bars are well suited to these locations, offering reliable mechanical strength for internal and semi-exposed doors.

By pairing ADI hardware with quality lever sets, knobs and cylinders from brands like Lockwood, Dormakaba, Barben and Zanda, you can maintain a consistent look throughout the building while tailoring the level of security to each door. This is ideal for commercial and strata environments where some doors require restricted access and higher resistance to tampering, while others simply need basic, robust locking.

For facility managers and builders working on schools, healthcare facilities, warehouses or residential developments, ADI products help deliver a secure, compliant and easy-to-maintain solution that stands up to frequent use.

 

Architectural Door Hardware for Residential and Commercial Projects

John Barnes Group specialises in architectural door hardware, and our ADI range forms a key part of that offering. These products are designed to integrate with modern door furniture, hinges, closers and access control hardware across residential and commercial projects. Whether you are fitting out a contemporary townhouse, a light industrial workshop or a mixed-use building, ADI hardware provides practical security without compromising on appearance.

Because ADI locking bolts, bars and lock boxes are generally surface-mounted or cavity-fitted components, they work well alongside premium handles and accessories from trusted brands. For example, you might pair ADI bolts with a sleek Zanda pull handle on an external door, or combine an ADI lock box with a Dormakaba or Lockwood key system for controlled access on plant room doors. Barben accessories in bathrooms and washrooms can also be coordinated to maintain a unified design language throughout the project.

The result is a cohesive, professional hardware package where aesthetics and security work hand in hand, helping you present a finished project that feels both secure and well considered.

 

Built for Australian Conditions

From the coastal air of Queensland and New South Wales to inland and regional sites across Australia, door hardware must withstand varied conditions. ADI door locks and bolts are designed for durability and long service life when installed and maintained correctly. Their robust construction makes them suitable for high-traffic doors in commercial environments as well as busy family homes.

When you buy ADI hardware online from John Barnes Group, you’re choosing products that are selected with Australian standards and typical local building practices in mind. Our team works with installers, builders and facility managers to help match ADI solutions to the environment, whether you’re dealing with external doors exposed to the elements or internal doors that see constant daily use.

Routine maintenance, including basic cleaning and periodic checks of fixings and alignment, will help keep ADI locking hardware operating smoothly and extend its service life, especially in challenging coastal or industrial environments.

 

Choosing the Right ADI Product for Your Door

Front and External Entry Doors

For front doors and main external entries, ADI locking bolts and security locks are often used as supplementary locks alongside primary key-in-lever or deadbolt sets. Choose robust models designed for solid core doors, and consider locks that project a strong bolt into the frame or locking body to resist jemmying and prying. This combination is particularly effective for residential and commercial doors that open directly to the street or public access areas.

Sliding Doors, Gates and Side Access

Sliding doors, side gates and secondary external doors benefit from compact but strong locking solutions. ADI surface bolts and specialised lock bolts provide positive mechanical locking for these openings, reducing the risk of doors being lifted or forced off their tracks. These are a great option for patio doors, courtyard entries and side access paths around homes and commercial properties in Brisbane, across Queensland and throughout New South Wales.

Commercial Facilities and High-Traffic Areas

In commercial environments, ADI locking bars and lock boxes shine where resilience and ease of use are essential. Use them on storerooms, plant rooms, service cupboards and back-of-house areas that require restricted access. When combined with master key systems from brands such as Lockwood and Dormakaba, ADI hardware supports secure, organised access control for staff and contractors while remaining straightforward to operate.

Integration with Existing Architectural Hardware

If you’re upgrading or extending an existing fit-out, ADI products can often be integrated with your current architectural hardware. Coordinate finishes with your existing matte black, stainless steel, chrome or brass door furniture from brands like Barben, Zanda and others to keep a consistent look across the project. This approach allows you to enhance security without needing to replace every handle or accessory in the building.
