Abstract
A poke-through wiring device and, more particularly, a self-anchoring poke-through wiring device which is positioned in a floor aperture of a concrete building floor for conducting electrical power and telecommunication signals between the work spaces of multi-storied building. The device incorporates anchoring clips in the shape of flat, essentially rectangular or polygonal non-resilient metal plates which are securely fastened by means of screw fasteners in surface contact with at least one plate of a sandwich-type fire retardant disc structure, and with the clips projecting radially outwardly thereof so as to have the outer edge or at least the corner of each anchoring clip severely bent and permanently deformed upon insertion of the wiring device into the floor aperture, thereby firmly contacting and grippingly engaging into the concrete wall surface of the perimeter of a floor aperture, and causing the entire poke-through wiring device or fitting to be firmly anchored in the aperture in a predetermined angular orientation relative to the aperture axis as required by the specific installation.
