Protective Cover for Trailer Hitch Ball (50 mm)

This trailer hitch ball cover is a simple yet effective accessory that keeps your towing gear in top shape. Whenever your trailer is unhitched, the exposed metal tow ball is subject to the elements – rain and moisture can induce rust, and grit or sand can contaminate the grease, potentially causing wear in the coupler next time you tow. By placing this plastic cap over the ball, you seal out the external environment, extending the life of the ball’s finish and ensuring smooth hitching every time.

Beyond protection, the cover also improves safety and cleanliness around your parked vehicle. Hitch balls are often lubricated for better coupling – without a cover, it’s easy to brush against it and soil your clothes or even injure yourself on the hard steel. The cover eliminates this issue by fully enclosing the protruding hitch ball. It’s extremely easy to use: the cap’s flexible material simply presses down over the ball and grips it firmly, so it won’t fall off even on bumpy roads. When you need to hitch up a trailer, just pop the cover off and stow it until next time.

Usage & Recommendations:

• Universal compatibility: Fits all standard 50 mm tow balls – cars, SUVs, vans with trailer hitches, regardless of hitch brand or type
• An ideal accessory for boat trailers and marine use, where saltwater and humidity can quickly cause corrosion – the cover protects the hitch ball during storage or when the trailer is not in use
• Tip: Put the cover on immediately after uncoupling your trailer – this keeps the grease clean and ready for next use, and keeps the cover’s interior clean as well
• Easy to clean – if the outside gets muddy or dusty, just rinse the cap with water and it’s good to go again
• Compact size: Store the cap in your glove box or trunk when towing – it takes virtually no space but is always handy when you need to cover the hitch again
