Abstract
A poke-through fitting, adapted to feed a cable or cables therethrough to a piece of furniture, including a raceway extending through the fitting, and a top portion which includes a medial portion including a plurality of sides each adapted to normally close the fitting, and to enable an opening to be formed therein to enable egress of the cable or cables, adapted to enable the volume of the cable or cables passing therethrough to be substantially greater than the volume of a cable or cables adapted to pass through a standard furniture feed poke-through fitting. The fitting is further adapted to be fire rated, including sealing elements, insulating elements, and radiating elements adapted to enable the fire-rating of the fire-rated floor to be substantially the same with or without the hole and fitting therein.
