Features & Benefits

8 Pre-Tapped Entry Ports: Engineered with 8 pre-tapped holes designed to accept standard 50 Series compression fittings or protective filler plugs (such as the 50830 plug), enabling clean and organized wiring expansion.
High-Impact Opaque Structural Body: Molded from an advanced, heavy-duty gray insulating plastic that handles severe road impacts, flying gravel, grease, oil, and aggressive commercial wash solvents without cracking.
Included Weatherproof O-Ring: Comes factory-equipped with a heavy-duty rubber O-ring seal to completely lock out moisture, heavy rain, road salt, and dirt, preventing the terminal corrosion that causes flickering commercial lights.
Vibration-Resistant 4-Hole Mount: Engineered for intense heavy-duty over-the-road demands, securing tightly via four mounting holes arranged perfectly on a $5\frac{1}{2}\text{-inch}$ diameter circle to resist severe chassis vibration.
Direct OEM Match: Serves as a perfect factory-fit replacement for damaged, cracked, or missing caps on existing Truck-Lite 50800 and 50801 junction box housings.
