Truck-Lite 45700 – 45 Series 3" x 5" Rectangular Open-Back Black PVC/TPR Mounting Grommet
Provide a secure, vibration-dampening foundation for your commercial vehicle lights with the Truck-Lite 45700 45 Series Rectangular Open-Back Mounting Grommet. Specifically engineered for flush mounting standard 45 Series lamps and 3.5" x 5" rectangular light fixtures, this heavy-duty accessory is an industry standard for vocational fleets, delivery box trucks, and regional semi-trailers.
Constructed from an advanced, premium Thermoplastic Rubber (TPR) compound and finished in sleek black, the Truck-Lite 45700 is designed to thrive in extreme, high-exposure environments. The specialized material composition eliminates "outgassing"—a process that can cause standard rubber compounds to cloud lenses and corrode internal connectors. Its smart open-back design allows ample space for complex wiring harnesses and direct plug configurations, making it a reliable, long-lasting replacement for aging or weathered light gaskets.
