Propping open fire doors is against safety regulations in the UK. This is because in the event of a fire, they form a crucial part of buildings' fire safety systems by helping to contain flames and slow the spread of smoke, providing critical time for evacuation and emergency response. At Slingsby, our fire door equipment includes a wide range of fire door hardware and fire door parts. Discover our range of standard door closers and advanced sound sensitive door retainers. These innovative devices keep doors open to support airflow or accessibility, but instantly release and close the door automatically when a fire alarm is triggered. With free delivery on all orders over £50* it's never been easier to equip your premises with compliant and high quality fire door solutions!
