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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
