Most of our rubber grommets and gaskets come in black. However, the Peterson 127-181 is a white grommet that gives a clean look to our 127 series lights when applied to a white trailer or truck body such as Knapheide. Many of our round grommets, shown online, are 2 inch grommets to 2 1/2 inch grommets. You can buy open-backed grommets or closed-back grommets depending on your application. Our 2 inch grommets, 2 1/2 inch grommets, and 4 inch grommets feature several grommet mount options, including: recess mount, edge mount, and flush mount.
