Abstract
A unitary insertable self-anchoring poke-thru wiring device for building construction includes a tombstone outlet box dimensioned to overlie and conceal a standard floor aperture opening into an occupied space, hollow elongated conduit means extending through the aperture, a narrow elongated junction box dimensioned to pass lengthwise through the aperture and anchored to the conduit means, fire-retardant means centrally anchored to the hollow conduit means positioned inside the aperture, and a conically-dished resilient spring washer encircling and anchored to the hollow conduit means adjacent to the fire retardant means and having its conical surface concavely diverging toward the outlet box, with its periphery notched and dimensioned for wedging engagement in the standard aperture, the poke-thru wiring device thus being adapted for unitary insertion from the occupied space into the aperture, with the resilient spring washer wedgingly engaging the internal wall of the standard aperture retaining the wiring device captively installed therein.
