Fire Hood Rectangular 1200 x 600mm – 60 Minute Fire Rated

Description

The Knightsbridge FR1200 is a rectangular fire hood measuring 1200mm x 600mm x 300mm, constructed from intumescent material to provide 60 minutes of fire protection for modular recessed luminaires fitted into ceiling voids. The hood fits around Knightsbridge MRA436xxxx series modular recessed fittings and contains fire spread by sealing the luminaire aperture when the intumescent lining expands under heat.

The FR1200 sits above the luminaire housing in the ceiling cavity, bridging the gap between the luminaire frame and the ceiling plasterboard. Internal metal rods span the hood’s length and bulldog-style clips attach the hood to the luminaire housing, holding it in place without additional fixing to the joists or ceiling structur
