ABSTRACT:
A mounting grommet intended for use in bores having sharp corners. The grommet includes a sleeve of hard material and a tubular, elastomeric element extending about and along the length of the sleeve. The element includes a cylindrical shank terminating at one end in an enlarged head. An axially extending recess is disposed in the head at its interface with the shank and the head has a generally frusto-conical surface on its side opposite the recess, the radially outer portion of the frusto-conical surface being located intermediate the ends of the elastomeric element. When applied to a bore in a rigid element having sharp corners, and compressed, the construction causes the recess to deflect radially inwardly at the corner so that there is no contact between the elastomeric element and the corner that would cause premature failure of the grommet.
