T-L 4" Lamp Grommet - Black

T-L 4" Lamp Grommet - Black

This is a Truck-Lite 40700 open-back mounting grommet, a standard component for heavy-duty vehicle lighting systems. It is used to install any standard 4" diameter lamp into a 4.5" mounting hole on the body panels of equipment like concrete mixer trucks. Operators need this part to replace old, cracked, or weathered grommets that no longer provide a secure fit or proper seal, or for new light installations. Made from durable black PVC, this grommet provides a clean, flush-mounted appearance and absorbs vibrations to protect the lamp and prolong its service life.
