# Fire-rate poke-thru assembly for quad receptacle

## Abstract

A fire-rated poke-thru (FRPT) device for routing power and low voltage through an opening in a concrete floor assembly. The FRPT includes a support plate including an opening configured for mounting of a quad receptacle and cutouts for attachment of a plurality of low voltage keystones. The quad receptacle includes a central body with four corners. The support plate is configured for mounting of a low voltage keystone at each of the corners of the quad receptacle. A section of electrical metal tubing extends from the support plate. The FRPT includes a top flange, a sliding plate, a bottom seal off, and one or more intumescent discs. The FRPT may be inserted within the opening in the concrete floor and secured thereto. If exposed to the heat from a fire, the intumescent discs will expand around the FRPT and prevent spreading of the fire through the floor opening.
