The i-CE Locking Systems Intumescent Self Adhesive Kit is specifically designed for enhancing the fire resistance of architectural tubular latches, with dimensions accommodating 100/127mm lengths. This 2mm thick FD60-rated kit includes self-adhesive intumescent materials that swell when exposed to high temperatures, effectively sealing gaps to prevent the spread of fire and smoke. The components appear self-coloured, likely in a dark grey or black shade, which implies no additional finishing. This kit is an ideal solution for fire safety compliance in commercial and residential buildings where tubular latches are used on doors requiring FD60 fire rating standards.
