Fire Door Kit – Office Locking Door (Severe Duty)
This Severe Duty Fire Door Kit has been engineered for the most demanding environments where doors are subject to constant use, misuse, and even abusive or violent operation. Designed, tested, and certified for FD30 and FD60 fire doors, it is ideal for public buildings, education, healthcare, leisure, and commercial settings with more than 40 occupants.
Supplied by Doorphoria, a trusted door supplier in Halifax and Huddersfield, this tradefit TF Grade 4 fire door kit meets the highest duty classification available. All components are tested to CE and UKCA Severe Duty standards and cycle tested to 500,000 operations, ensuring exceptional durability and long-term performance.
A key feature of this kit is the cam action overhead slide arm door closer, which significantly reduces the force required to open the door. This improves accessibility, reduces strain on users, and minimises wear on handles and locks. The non-projecting slide arm design improves safety, prevents objects being hung from the door, and offers a clean, modern appearance.
The kit also includes concealed self-lubricating bearing fire door hinges, which automatically lubricate with each door movement. This reduces maintenance requirements and extends hinge life in high-traffic environments. Combined with a DIN mortice euro sashlock, anti-pick cylinder and turn, and return-to-door lever handles, the kit delivers secure, reliable operation day after day.
Finished in satin stainless steel, this fire door kit suits modern commercial interiors, industrial style doors, and robust public-use environments. Backed by an industry-leading 25-year mechanical guarantee, it provides complete confidence that properly tested, accredited ironmongery has been installed for severe duty use.
