A small part that makes a real difference. The Camco 40302 bumper cap snaps onto the open end of a 4-inch square RV bumper tube, keeping out road debris, water, insects, and dirt. Whether your original cap cracked, blew off at highway speed, or just went missing, this is the straightforward replacement you need -- one cap, correct size, ready to install.
Most RV rear bumpers are hollow square steel tubes. Without an end cap, that open tube collects rainwater, mud, road grime, and pests. Many RVers store sewer hoses or fresh water hoses inside the bumper tube, which makes keeping that space clean and dry even more important.
The Camco 40302 is molded from durable black polyethylene with ribbed outer edges that grip the inside of the bumper tube opening firmly -- no adhesive needed. A small vent hole in the cap face allows air circulation, which helps prevent trapped moisture and condensation from building up inside the tube.
Textured outer ribs press against the inner walls of the bumper tube to hold the cap securely in place without screws or glue.
A small vent hole in the face of the cap allows air to circulate inside the bumper tube, reducing moisture and condensation buildup.
Molded from black polyethylene for UV resistance, weather durability, and long-term outdoor use without cracking or fading quickly.
Simply align the cap with the open end of your 4-inch square bumper tube and press firmly until the ribbed edges seat. No hardware required.
This cap is designed for 4-inch square hollow bumper tubes, the most common bumper tube size on travel trailers, fifth wheels, and Class A and C motorhomes. The cap measures 4 inches x 4 inches and is sold as a single unit. If your RV bumper has two open ends -- one on each side -- you will need to order two caps.
Before installing, clear any debris, standing water, or dirt from inside the bumper tube opening. Press the cap straight in -- do not angle it -- so all ribbed edges make even contact. If the fit feels loose due to a worn or oversized tube opening, a small bead of silicone sealant around the exterior edge can help secure it.
The Camco 40302 is a direct drop-in replacement for original-equipment bumper caps on most travel trailers and motorhomes using 4-inch square bumper tubes. Keep a spare on hand -- these lightweight caps can blow off at highway speed if the press fit loosens over time due to tube wear or impact damage.
