Replacement rubber bumper plug for most RV bumpers with a 4" cut out, without mounting tabs. Includes a small air-circulation hole and fits snugly with a 3-3/4" collar.
The JR Products 358-A is a rubber bumper plug built to replace a lost or broken bumper end cap on most RV bumpers with a 4" cut out, without the mounting tabs found on JR Products' tabbed version. It's commonly used to help keep sewer hoses and other bumper-stored accessories in place, with a small hole in the cap allowing air circulation to reduce condensation buildup. Made from high-impact rubber that resists shrinking and fading, it fits snugly with a 3-3/4" collar and is easy to insert and remove.
