Locks and latches can play an important role in how a building looks, operates and performs day to day. The right product helps improve usability, protect surrounding finishes, support access requirements and reduce maintenance issues over time. John Barnes Group makes it easier to compare product types, sizes, functions and finishes in one place.

Choose the Right Locks & Latches for Your Project

The best locks and latches will depend on the application, surrounding materials and expected level of use. Key selection factors include door type, lock function, backset, handing, cylinder type, security level, fire or egress requirements and compatibility with the selected handles. Taking the time to match the product to the site helps avoid installation issues and ensures the finished result works properly in everyday use.

It is also important to consider who will use the opening or space each day. A private home, public washroom, office, warehouse, school or healthcare facility may all require different levels of durability, security, visibility, maintenance access and ease of operation.

Types and Options Available

Our range includes mortice locks, tubular latches, deadbolts, nightlatches, privacy locks, strike plates, rebate kits and lock accessories. This gives builders, facility managers, locksmiths, designers, homeowners and maintenance teams practical options for both new installations and replacement work.

Correct lock selection helps improve security, usability and long-term door performance. For commercial and high-traffic environments, stronger construction and appropriate fixing methods are especially important. For residential and design-led projects, profile, finish and coordination with surrounding hardware can be just as important as basic function.

Residential, Commercial and Project Applications

Locks and latches are used across homes, apartments, offices, schools, healthcare facilities, retail spaces, hospitality venues, industrial sites and public buildings. In residential settings, they help improve everyday convenience and create a more finished appearance. In commercial settings, they support durability, access, safety, maintenance and long-term building performance.

For project work, consistent product selection can save time and reduce mismatched finishes or incompatible components. Selecting suitable hardware across multiple openings, rooms or buildings helps create a cleaner specification and a more professional result for the end user.

In maintenance and refurbishment work, matching the replacement product to the existing door, frame, panel, gate, window or washroom layout is just as important as choosing the right finish. Checking measurements and compatibility early helps avoid delays once the job is on site.

Finishes, Materials and Hardware Coordination

Many products are available in practical finishes and materials to suit modern, classic and commercial interiors. Depending on the category, popular options may include matte black, satin chrome, polished chrome, stainless steel, satin nickel, brass tones, white finishes or other architectural finishes. Choosing the right finish helps the hardware blend with surrounding doors, frames, joinery, washroom fittings, gates or window hardware.

Where possible, it is worth coordinating visible hardware across the project. Matching finishes and related profiles can improve the overall appearance while making future maintenance and replacement easier to manage. This is particularly useful when a project includes multiple product types, such as door hardware, washroom accessories, gate hardware, window hardware or electronic security components.

Practical Selection and Installation Notes

Before ordering, check the relevant measurements, fixing points, handing, clearances, material compatibility and any project-specific requirements. Small differences in size, function or installation method can affect whether the product fits correctly and performs as expected.

For commercial, security-related, accessible, fire-rated or compliance-sensitive projects, it is worth confirming the specification before installation. Professional installation is recommended where incorrect fitting could affect safety, security, warranty, durability or daily operation.

Can locks be used with different handle styles?

Many locks and latches work with a range of handles, but compatibility should be checked before ordering.

Are locks suitable for fire doors?

Some locks are suitable for fire-rated applications, but the complete door assembly and project requirements must be considered.

Professional installation is recommended for entrance, commercial, keyed, fire-rated and security-related locking hardware.
