Uxcell 60-Pack Rubber Grommets – 5/16" ID, 3/8" Drill Hole, Dual-Sided Frosted Design For Wire & Cable Protection

About This Product

If you're running wires through metal panels, electrical boxes, or furniture, you know that raw edges can chew up cables and cause shorts.
These uxcell rubber grommets are a super simple fix – they turn sharp, rough holes into smooth, insulated openings that protect your wires and keep everything tidy.

You get 60 pieces in one pack, each with a 5/16-inch inner diameter and designed for a 3/8-inch panel hole.

The outside diameter is about 0.

59 inches, with a groove width of 0.
08 inches and an overall thickness of 0.
24 inches.
That size fits a wide range of common applications – from automotive firewall pass-throughs to computer cases, speaker cabinets, and even plumbing projects.

The rubber is flexible yet durable – strong enough to resist heat, cold, aging, corrosion, and even flame.

And the frosted surface on both sides is a nice touch – it reduces fingerprint smudges and stays cleaner-looking than shiny rubber.

Installation is easy: just measure your panel hole, pop the grommet in, and slide your cable through.
They hold tight and don't slip out, so your wires stay organized and protected.

Whether you're a professional electrician, an automotive hobbyist, or just someone who likes to keep things neat, these grommets are a handy, affordable addition to your parts bin.
