Abstract: A grommet assembly useful in attaching articles to a carrying structure includes a first and second annular grommet piece, each conformed for mating engagement to the other, the first grommet piece including a central boss extending axially from one side of an annular base provided with a tapered cavity therein. The second grommet piece is similarly provided with an axial boss tapered on the exterior to fit within the cavity. The free edge of the second boss includes a peripheral bead conformed to engage an interior recess in the cavity. The grommet pieces may be joined to each other by a flexible strap and the first piece may include a bedded washer on the surface opposite to the first boss. Both the grommet pieces and the strap may be formed of a resilient material structure and when the bosses are mated in each other the subsequent compression of the assembly will expand the combined sectional dimension thereof for compressing against the surfaces of any suspension device.

Abstract: A resilient grommet assembly useful in isolating the transfer of acoustical energy across structural connections includes a first annular portion provided with a central tubular projection in concentric deployment within a first peripheral edge and a second, mating annular portion provided with a second peripheral edge, the first edge extending to a depth greater than the second edge. The tubular projection is then inserted into a circular hole in a hanger strap and thereafter into a central opening in the second portion. A fastener then compresses the portions against the hanger and since the depth of the first edge is greater than the second edge the first edge is collapsed to a greater extent to further drive the tubular projection into the second portion.
