Heavy-Duty Fire Door Closer for High-Traffic Environments
When doors are larger, heavier, and used more frequently, standard closers aren’t enough. This fire door closer power size 3–6 is built for demanding environments where safety, durability, and smooth control are essential.
Supplied by Doorphoria, a trusted door supplier in Halifax and West Yorkshire, this closer is ideal for commercial buildings, HMOs, offices, hotels, bars, leisure venues, warehouses, and public spaces.
It pairs perfectly with internal fire doors, fully finished internal doors, and commercial steel door sets used across the UK.
Designed for Heavy Doors & Frequent Use
With an adjustable power size range of 3–6, this closer supports doors weighing 40–120kg and up to 1400mm wide. Power adjustment is achieved by positioning the closer on the door, allowing installers to fine-tune performance on site.
The rack and pinion mechanism delivers consistent closing force, even on heavy doors subject to constant use. Rated TF Grade 3, it’s suitable for environments with a high risk of misuse and limited user care.
Delayed Action & Backcheck for Safety and Control
This closer includes both delayed action and adjustable backcheck, making it suitable for busy corridors and access routes.
-
Delayed action slows the closing cycle, giving users more time to pass through
-
Backcheck prevents doors from flying open when pushed forcefully or caught by wind
-
Adjustable closing and latching speeds ensure reliable fire door performance
These features help protect door frames, hinges, walls, and surrounding finishes while improving accessibility.
Fire Tested, Certified & Built to Last
Safety is non-negotiable. This closer is EN1634 tested and approved for:
-
Timber fire doors: FD30, FD60, FD90 & FD120
-
Steel fire doors: Up to 240 minutes
It is CE and UKCA approved and supplied with a 10-year mechanical guarantee, giving installers and property managers long-term confidence.
Finished in a clean silver powder coating, it integrates easily with modern interiors, industrial style doors, and commercial hardware schemes.
