Metallics HG38 – Frequently Asked Questions
1) What size hole does the Metallics HG38 grommet fit?
The HG38 vinyl hole grommet is sized 3/8 x 43/64. The 3/8 inch figure is the inside opening the wire or cable passes through, and 43/64 is the second dimension given for the grommet. Order by the part number HG38 to get that size.
2) What is a vinyl hole grommet used for in an electrical box or metal panel?
It lines a drilled or punched hole so the metal edge does not cut wire insulation where conductors pass through. The Metallics HG38 is a vinyl grommet, so it is an insulating bushing rather than a clamp, it protects the cable but does not secure it. If you need the cable held in place, use a connector or cable clamp instead.
3) I keep a bin of electrical rough-in parts. Does the HG38 come in more than one size on the same part number?
No. HG38 is a single size, 3/8 x 43/64, with one model offered. If your panel or box has a different knockout, you need a different grommet part number, not a variation of this one.
4) Is the Metallics HG38 grommet rubber or plastic?
Vinyl. The HG38 is a vinyl (Vyl) grommet, which is flexible enough to snap into a punched hole and stay seated without adhesive or a separate retainer.
