Suitable for FD30, FD60, FD90 and FD120 timber doors, and FD240 steel doors, up to 160kg weight. Designed for use in areas where there is a clearly identified risk of self harm. Anti-Ligature hinges provide a discreet and effective solution by greatly reducing the possibility of the hinge knuckle projection being used as a ligature point. Intumescent Hinge Pads MUST be used on fire doors for full compliance to BS EN 1634 & BS EN 1935. Sold in packs of 6 (enough for 3 hinges 1½ pairs). Our monoammonium phosphate-based intumescent hinge pads ensure virtually no compression when fitted, unlike the cheaper, more malleable graphite-based pad that is easily compressed, allowing screws and fixings to work loose. When subjected to heat, the monoammonium phosphate-based pad expands at a lesser heat range than the malleable graphite-based one, thus preventing toxic fumes from passing sooner. Also available in other finishes.
