About this detail

A cable tray penetrates a fire-rated partition and a concrete masonry unit or concrete wall. Insulated cables are supported in a steel cable tray bedded in fire-rated sealant in accordance with the rated assembly. An intumescent wrap strip is installed at the perimeter of the cable tray, complemented by an intumescent sheet on the underside. Fire-rated sealant seals the perimeter of the entire penetration opening. The gypsum partition assembly provides a maximum two-hour rating under UL W-L-4004, while the concrete and concrete masonry unit wall assembly provides a three-hour rating under UL C-AJ-4003.
