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.
