Abstract: The invention comprises a sealing grommet having a body made of an elastomeric material. The body has two halves to be assembled together in a sealing arrangement. The halves have a cable receiving opening extending therethrough from one side to another side. The opening has an outer diameter with a series of pliable webs extending inwardly into the opening to form a cable receiving channel. The webs in a center of the halves are larger and extend further into the opening than the webs along the sides of the halves thereby making the channel narrower in the center of the halves than along the sides of the halves to enable a sealing relationship to be formed about a variety of cable sizes.
