Abstract
Poke-thru has floor fitting serviced by a thru floor unit in a bore in the floor and carries power and/or communications conductors. The thru floor unit comprises a pair of mounting screws which extend down through the floor fitting base with the heads engaging the base. The mounting screws carry a flexible finger type retaining clip to grip the side of the bore. Above the retaining clip, on the mounting screws, are top separator means which maintain the clip and base a fixed distance apart. Intumescent material and a top spacer are loosely disposed in the space between the clip and the base. Below the retaining clip, on the mounting screws, is a bottom spacer. Below the bottom spacer are top and bottom retainers held a fixed distance apart by separator means. Intumescent material is loosely disposed in the space between the top and bottom retainers. The bottom retainer has nuts in which the screws are threaded.
