grommet, 4 inch rubber
The grommet, 4 inch rubber fits most standard 4 inch lights. It is a soft, flexible material, allowing you to easily pop a grommet into the light holes you cut in your truck or trailer. Once in, however, they form a tight seat so your lights fit firmly. For a 4 inch grommet, you need to drill a 4½” hole in the where you are planning to mount the light. The rubber 4 inch grommet fits the red, TL4050, and the amber, TL4050A. You can buy plastic chrome grommet covers, UP10484, to cover the rubber grommets at our website, too.
