Customer Reviews (4.4 / 5 · 5 reviews)

Hazel M. ★★★★★

Installed these in a 16-gauge steel panel and they seated firmly without any extra effort. The rubber has a nice pliable feel but still holds its shape well in the hole.

Eva Q. ★★★★★

These Buna-N grommets fit perfectly into my 5/16" holes and that 0.312" ID is just right for the cables I'm running. The rubber feels dense enough to hold up well against vibration.

David ★★★★★

Exactly what I needed for a quick wiring panel job — the 0.312" ID fits my 1/4" cable perfectly and the black Buna-N rubber feels durable. No issues with the 0.062" panel thickness spec either. Happy with this pack of 150.
