The improper installation of fire door hardware can compromise the safety and effectiveness of a fire door. The reliability of fire doors can quickly become compromised by hardware alignment issues and improper installation. If door hardware is not installed correctly, a fire door may fail to latch or close fully from its standing position, leaving gaps that allow flames and smoke to pass through during a fire. Should this be the case in your building, you could be invalidating the fire door’s certification and putting occupants at risk. It is important to remember that fire door hardware installation requires specialised expertise, and it is recommended to plan carefully and seek professional guidance when needed.
During installation, installers need to adhere to the manufacturer’s guidelines and fitting instructions, which are typically provided with all third-party-certified fire doors and hardware. Fire door hardware products are often unique to the manufacturer, with distinctive components, fittings and fixing points.
In many instances, even a well-specified and fully functional door closer can become ineffective solely due to improper installation.

Frequently Asked Questions
How does improper fire door hardware installation affect safety? Poor installation can prevent a door from latching or closing fully, leaving gaps that allow smoke and flames to pass through. That can void the door’s certification and put people at risk, so fix alignment or fitting errors quickly and follow the manufacturer’s instructions.
Who should install fire door hardware? Use a competent, trained installer who understands third-party certification and the specific manufacturer’s fittings. They should follow the supplied instructions, record their work, and provide certification when required.
Can a correctly specified door closer fail because of installation? Yes. Even a certified closer can perform badly if mounted incorrectly, misaligned or secured with the wrong fixings. Check the fitting, arm position and alignment during installation and after any adjustments.
What are the key steps for a reliable door closer installation? Follow the manufacturer’s template and instructions, position the closer and arm per the specified mount type, tighten fixings to the correct torque and test that the door closes and latches from a small opening. Finish with functional checks and retain the installer’s records.
How can installers make installations faster and more accurate? Use self-adhesive templates and the manufacturer’s instructional videos to reduce guesswork. Measure, dry-fit, test operation, and tweak settings on-site so the closer works correctly the first time.
