ABSTRACT:
A plastic grommet for use on metal studs in wall construction protecting wires, cabling, conduit, and the like. The grommet also makes the passing of such utilities easier and quieter. The grommet will function singularly or assembled to a clone. The grommet includes a cylindrical body having an enlarged flange on one end with radially projecting spring snaps on the exterior of the body whereby the grommet may be inserted in a sized hole in the web with the hole edge captured between the snaps and flange. On the other side of the flange are diametrically opposed axially projecting spring fingers. The flange also has two diametrically opposed holes, the fingers and holes being positioned so that two grommets can be joined flange-to-flange by axially rotating one with respect to the other. Two such grommets thus assembled on opposite sides of a rectangular or other irregular or pre-punched hole in the stud web capture the web between the flanges.
