4-inch square RV bumper cover, made of aluminum alloy, designed for the square bumper opening at the rear of an RV. The interior of the bumper is typically used to house the RV’s wastewater hose.

External Structure Analysis

1. Flip-top panel with ventilation holes: The panel is covered with diamond-patterned ventilation holes designed to allow airflow and dispel odors, preventing the sewage hose inside the bumper from becoming stagnant and smelly; metal hinges are mounted on the sides of the panel, allowing it to flip open outward.

2. Hinges: The black hinges on the right side of the product enable the flip-top to open and close; there is no need to remove the entire bracket—simply open the cover to access the sewage hose inside.

3. Anti-Loss Lanyard + Quick-Release Clip: The left side features a steel cable and a carabiner. When the flap is open, the flap can be secured to the lanyard to prevent it from being lost or falling off during bumpy drives.

4. Mounting Bracket: The snap-on bracket at the rear of the product clamps directly onto the end of a standard 4-inch square RV bumper for easy installation.
