2 1/2 inch Open Back Flush Mount Grommet

This Open Back Flush Mount Grommet accommodates sealed, 2 1/2 inch round clearance, identification, or marker lights on trailers, commercial trucks, and RV chassis. Made of durable, black PVC rubber, it stands up to road salt and wet, cold, or hot weather extremes. 

That rubber material also makes it easy to install. If you have a 3 inch hole drilled in the frame of your vehicle, this grommet pushes in smoothly. With the help of a strong but flexible outer lip, it grips the edge of your hole. 

You can push your round light in effortlessly, and it sits flush and level with your grommet. Meanwhile, a round hole at the back of the grommet leaves the electrical prongs exposed for quick hookup to your wiring harness.  

This Open Back Flush Mount Grommet’s construction gives it a long life. Additionally, its vibration absorption does the same for sealed lights, protecting incandescent or LED lights from breaking under rough-road conditions. 

Its standard dimensions make it an excellent replacement for other manufacturers’ grommets, including:

• Grote # 91410 
• Peterson # 142-18
