Product Details

The Optronics A45GB is a durable PVC grommet designed for flush mounting 4-inch round trailer lights. This black grommet provides a secure, professional installation while protecting your lights from road vibration and impact.

Key Features:

  • Fits 4-inch round trailer tail lights and work lights
  • Requires 4-1/2 inch diameter mounting hole
  • Shock mount protection extends lamp life by absorbing vibration
  • Durable PVC construction resists weather and road chemicals
  • Built-in lip design holds grommet securely in place through metal panels
  • Open back design allows easy access to wiring connections
  • Outside diameter: 5-1/4 inches
  • Compatible with Optronics 4-inch round lights and Peterson B426-18

Ideal for trailer chassis, bumpers, and flat mounting surfaces. The grommet's contoured design hugs both the light fixture and mounting panel, creating a tight seal that keeps the assembly locked in place during vehicle movement. Can be paired with Optronics chrome trim ring (A45CGB, sold separately) for a finished appearance.
