Abstract
A floor box assembly includes a floor box, a mounting plate, a below-floor insulation kit, and an intumescent stem. When the floor box is installed on a floor deck having flutes and valleys, the mounting plate straddles one or more valleys and supports the floor box. The below-floor insulation kit closes off the flutes adjacent to the valley straddled by the mounting plate, and the intumescent stem penetrates the floor deck at the bottom of the valley. When installed, the floor box assembly is held together by attachment fasteners extending from the mounting plate through the floor deck and the below-floor insulation kit.
