Grote 91400 Open Back Mounting Grommet for 2-1/2" Round Lights – 2-25/32" Hole Size

The Grote 91400 Open Back Grommet is the industry-standard mounting solution for 2-1/2 inch round clearance and marker lamps. Designed to provide a secure, vibration-dampening fit, this grommet is essential for ensuring your vehicle’s lighting remains intact through the rigors of heavy-duty use. Whether you are outfitting a new trailer or replacing worn-out hardware, Grote’s PVC grommets offer the durability and precision fit required by professional fleets.

Manufactured from high-quality, flexible black PVC, the 91400 grommet is built to withstand extreme weather, road chemicals, and UV exposure without cracking or hardening. Beyond holding the light in place, the resilient material acts as a shock absorber, protecting internal bulb filaments or LED circuits from road vibration. This specialized design extends the overall service life of your lighting equipment and reduces long-term maintenance costs.

This grommet is engineered specifically for 2-1/2" round lamps and fits into a 2-25/32" diameter hole. Its open-back design allows for easy wiring access, making it the perfect choice for installations where a splash plate is not used. The flush-mount profile provides a clean, professional appearance on panels up to 1/8" thick, making it ideal for trucks, trailers, and utility vehicles.
