Abstract

A conical hole plug for efficiently sealing various size and configuration holes and openings. The conical hole plug generally includes a first elongated portion including a first inner end and a first outer end, wherein the first inner end is opposite the first outer end and wherein the first elongated portion includes a first tapered outer surface extending inwardly toward the first outer end. A second elongated portion extends from the first elongated portion, wherein the second elongated portion includes a second inner end and a second outer end, wherein the second inner end is opposite the second outer end and wherein the second inner end extends from the first inner end and wherein the second elongated portion includes a second tapered outer surface extending inwardly toward the second outer end.
