What it does

  • Hides Ethernet and AV cables through drywall cleanly
  • Fits a 25mm hole-saw cut for fast install
  • Looks finished from both sides of the wall
  • Saves the patch-and-paint job on a rough hole

Pass cables through a drywall opening like a pro. This grommet drops into a 25mm hole-saw cut and frames the opening on both sides, so Ethernet, HDMI, or audio cables slide through without showing the rough drywall edge.

Adjust the OD by editing the source if your hole saw is slightly different. The grommet stays put under cable pull, so connections stay clean and your wall stops looking like a DIY accident. A small finish piece with a real polished result.

Built for home theater installs, network drops, and anyone routing cables behind walls. The kind of small fix that quietly turns a rough job into a tidy one.

What it is made of

Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
