CURT 21728 Rubber Trailer Hitch Cover with 4-Way Flat Wiring Holder — 2-Inch Receiver

Keep your trailer hitch ready for action with the CURT 21728 Rubber Trailer Hitch Cover. This durable cap is designed for a 2" x 2" receiver tube, giving you a clean, protected opening when you’re not towing. The rugged black rubber resists the elements, helping your hitch look sharp and stay serviceable for longer between uses.

Beyond simple coverage, this CURT hitch cover brings practical, thoughtfully designed features that fit real-world towing needs. Its friction-fit installation means you don’t need tools to install or remove it, so quick changes between tasks are straightforward. A built-in bracket permanently mounts over the receiver tube, so the cover won’t wander or get misplaced when you take a break from towing. The integrated 4-way flat wiring connector holder keeps your electrical connector secure and on-hand, reducing the chance of snagging or misplacing it in the mud or snow.

What you get and how it helps your rig

Designed as a complete towing solution, the CURT cover keeps the hitch tube clean and ready. The built-in bracket helps you prevent misplacement, while the wiring holder ensures the 4-way connector stays organized. When it’s time to tow, simply remove the cover and proceed as usual—the tube and connector stay protected during downtime.

Real-world use includes seasonal storage for off-road setups, protection during inclement weather, and everyday tidiness after trips through dusty or muddy conditions. The tactile rubber texture offers a solid grip for easy removal and replacement, while the subtle black finish complements most vehicle aesthetics.

Compatibility notes: this cover fits standard 2x2 receiver tubes common on many Class 3–5 hitch systems. For care, a quick rinse and light dry will help maintain flexibility and appearance over time.
