The design of a building requires a delicate alchemy of aesthetics and functional characteristics which make it fit for purpose.
A specifier’s responsibility is to curate the materials to meet all required standards and performance criteria – so an eye for detail, coupled with an intricate understanding of the bigger picture, is key.
Tracy Logan, Sales Advisor at Zoo Hardware, explains how the various mechanical components installed on doors to ensure their proper function can have a far-reaching impact – highlighting some common misconceptions and misunderstandings around their proper specification.
It is important for a manufacturer to be a specifier’s trusted partner in this process, sharing knowledge and insight to help guide the specification process, particularly in an era shaped by the Golden Thread and Building Safety Act.
For the most part, door hardware is an afterthought for the end user – most of us will only passively engage with hinges, locks and closers.
For a specifier, however, these are the details which need to be properly considered – proper specification, installation, and ongoing management of door hardware factors in to fire safety, accessibility, and securitywhile maintaining compliance with legal requirements.
Certification and Compliance
There are a few key considerations to keep in mind to ensure that the door hardware you specify will meet the Building Safety Act requirements, including the Golden Thread which is a core requirement under the Building Safety Act 2022.
Use certified and compliant hardware – Always specify products tested to BS EN and British Standard (BSI) Kitemark requirements when applicable.
Maintain accurate records – Store installation, maintenance, and inspection details in a digital format for easy access and verification.
Regular inspections and maintenance – Ensure door hardware is routinely checked to prevent failure, especially for fire doors and emergency exits.
Training and awareness – Facilities managers and responsible persons should be trained to identify hardware failures and compliance gaps.
Common Pitfalls
As a leading manufacturer of door hardware, there are a few common issues we encounter across the specification and installation processes that can compromise performance and compliance.
These include:
Working with the Right Specification Information and Support – Accurate door hardware specification depends on key details like door height, width, weight, fire rating, and closer type.
Missing this information or using inaccurate data can lead to poor performance, costly replacements, and compliance issues—especially in retrofits where existing conditions affect compatibility.
Partnering with knowledgeable suppliers ensures the right product choices – Zoo’s GAI-certified experts provide guidance backed by rigorous procuct testing, setting them apart in the industry.
Their support helps specifiers navigate regulations, durability needs, and aesthetic considerations, reducing risks and ensuring smoother project execution.
Lever Installs – One of the most common pitfalls in lever handle installation is the failure to use bolt-through fixings. Many specifiers and installers rely solely on face-fixed screws, assuming they will provide sufficient stability.
However, over time, frequent use and operational stress can cause these screws to loosen, leading to misalignment or even complete failure of the handle. Bolt-through fixings ensure a secure attachment by distributing force across the door rather than just the surface, significantly enhancing durability.
Specifiers should always check that the hardware specified includes these fixings and that installers follow best practice to prevent premature failures and costly remedial work.
Finishes – Lacquered finishes have evolved significantly, but their longevity still depends on proper maintenance. Over time, exposure to environmental factors, cleaning chemicals, and heavy use can cause lacquer coatings to wear, leading to tarnishing or discolouration.
Specifiers should educate end-users on the importance of appropriate cleaning methods and periodic maintenance to prolong the life of lacquered hardware.
An alternative to traditional lacquered finishes is Physical Vapour Deposition (PVD) coatings, which offer superior durability and resistance to corrosion, making them ideal for high-traffic and external applications.
While PVD finishes require minimal maintenance compared to lacquered options, they still benefit from regular cleaning with mild, non-abrasive solutions to preserve their appearance.
By considering these factors early in the specification process, specifiers can ensure the chosen finish aligns with the project’s performance and longevity expectations.
Fitting Errors – A frequent and avoidable issue in door hardware installation is the omission of critical components provided in the installation box. Items like lock fixings, spindle supports, and dust boxes may seem insignificant but play a vital role in the overall performance of the hardware.
For example, dust boxes help maintain a clean and smooth operation of latch mechanisms, reducing wear over time. When installers overlook these components, it can lead to operational issues such as misalignment, difficulty in latch engagement, or even premature hardware failure.
Specifiers should emphasise the importance of following manufacturer installation instructions and ensure that all necessary components are included in procurement and installation checklists. By doing so, they can mitigate performance issues, reduce callbacks, and enhance client satisfaction.
Summary
Ultimately, door hardware may seem like a small detail in the grand scheme of a building project, but its impact on functionality, security, and safety is profound. By prioritising correct specification and installation, specifiers can contribute to a built environment that upholds the highest standards of compliance, durability, and user satisfaction.
By understanding and addressing these common pitfalls, specifiers can significantly improve the performance, safety, and longevity of door hardware in their projects. The key lies in selecting certified products, maintaining detailed records, conducting regular inspections, and ensuring proper installation practices.
Collaboration with knowledgeable suppliers, like Zoo Hardware, can make all the difference, offering expert guidance and support to navigate complex compliance requirements.
