Sturdy metal construction Made from high-grade metal, this cover delivers greater strength and security for your drainage hose compared with typical plastic options. Compatibility with RV trailers Fits most RV trailers with a 4-inch square bumper, allowing you to keep your sewer hose neatly tucked away for a clean exterior appearance.
