The Liobex DA 150mm Double Action Spring Hinge Silver Enamelled is a double action hinge for fire doors – it will allow the door to open in either direction and will return the door to the closed position. Spring hinges have gained popularity in dwellings which require self-closing fire doors such as swing action to kitchen or wash-up area doors in restaurants, public houses, flats and multiple storey town houses. The hinge is to suit doors 25-44mm thick, 930mm wide and with a maximum weight of 42kg assuming the whole set is being used.
Each set of hinges comes with tensioning pins, which are inserted into the knuckle of the hinge, once fitted, to tension the internal spring mechanism. The spring tension and closing force is controlled by the location of the pin into pre-determined holes around the hinge knuckle.
Other Variations
It is available in 200mm (for doors 35-55mm thick, up to 1000mm wide, max 55Kg) It is also available in a satin stainless steel finish. Please get in touch for more information.
Fire Door Hinge
Although the other variations of this double action spring hinge are not approved for use on fire door openings, this 150mm option is suitable for use on fire doors.
Change to Building Regulations
As of 6th April 2007, it is no longer a building regulations requirement that a self closing device, such as a perco or spring hinges, be fitted to internal fire doors in dwellings. It has become the responsibility of the occupants to ensure that fire doors are closed at night. Closing devices are still required on flat entrance doors and garage doors leading into a dwelling. However, these closers now have to comply with BSEN 1154, which currently means they need to be overhead door closers. If in any doubt, please discuss the matter with your Building Control Officer before commencing any work.
