Simplify and secure your commercial fleet's lighting installation with the heavy-duty Truck-Lite 50831 4-Inch Round Gray ABS Flange Mount. Serving as a versatile mounting adapter ring, this high-impact structural component allows you to seamlessly install 4-inch diameter round lamps into specialized cutout spaces. Engineered to convert a larger 4.75" hole layout down to a standard 4.5" opening, it provides a stable, highly reliable interface that ensures your tail lights, turn signals, and marker lamps stay perfectly aligned and tightly flush against your vehicle.
Time-Saving Adapter Design: Acts as a specialized conversion ring that instantly down-sizes a 4.75” surface hole to a 4.5” dimension, eliminating the need for custom fabrication or bodywork.
High-Impact ABS Construction: Molded from premium-grade gray ABS plastic that effortlessly absorbs severe road impacts, flying gravel, and structural chassis stress without cracking or warping.
Weather & Heat Defiant: Thermally stable and chemical-resistant composition prevents degradation from constant exposure to harsh UV rays, road salt, grease, oils, and aggressive commercial fleet solvents.
Vibration-Resistant Flange Mount: Delivers a secure, locked-in mounting platform for round-shaped vehicle lights, absorbing heavy over-the-road vibration to extend the life of your underlying LED or incandescent bulbs.
Direct Industry Replacement: Functions as the perfect direct-fit replacement for the legacy Signal-Stat 9117 flange mount, making fleet retrofits fast and seamless.
