Abstract: A grommet has a faceplate with a width that is greater than an aperture width in a metal stud, as well as a front surface and a rear surface that extend downwardly to form a first clip portion. The grommet also includes a flange extending from a perimeter of an opening through the faceplate, to form a duct shaped to receive the flex tubing therethrough. A second clip portion extends downwardly from the flange, adjacent the first clip portion, so that the first and second clip portions frictionally engage the metal stud to hold the duct within the aperture of the metal stud.
