Uposao trailer hitch ball cover – Black, 50 mm
A simple, sensible bit of kit that saves you a load of faff further down the line. This Uposao trailer hitch ball cover just slips over a standard 50 mm (2″) tow ball to keep dirt, grit and moisture out — very handy in winter or after a trip to the coast when salt can start eating at the metal. It’s moulded from ABS (acrylonitrile butadiene styrene), so it’s waterproof, dustproof and tough enough for everyday use.
what it is
The cover is an easy push-on cap made for trailer hitch balls with an inner diameter of 50 mm (2″). It’s featherweight at roughly 40 g but built to last, acting as a simple barrier against corrosion and road debris. No fiddly fittings or electrical bits — just a straightforward protective cap you can pop on and forget about until the next tow.
key features
- Reliable fit for 50 mm (2″) tow balls – compatible with most car, caravan and trailer hitch balls.
- Made from ABS (acrylonitrile butadiene styrene) – durable, weather-resistant and ageing-resistant.
- Waterproof and dustproof – keeps the ball clean and cuts down on maintenance.
- Lightweight and compact – easy to stash in the glovebox or toolkit when not in use.
- Quick push-on installation – no tools required, fits or comes off in seconds.
why it helps
Leaving a tow ball exposed means dirt, rain and road salt can build up and speed up rust — which makes hitching up messier and sometimes noisy. A small cap like this avoids scraping and constant cleaning, keeping the ball in good nick for longer. If you only tow now and then, or you use a caravan, it’s one of those low-cost bits that saves time and worry.
typical uses and compatibility
- Cars and estate cars with detachable tow balls – ideal for protection between uses.
- Caravans and trailers – handy for storage or when parked up for long periods.
- Trucks, RVs and agricultural trailers – useful wherever a 50 mm ball is fitted.
- Coastal and winter conditions – helps reduce corrosion from salt and grit.
If you’re unsure about fit, it’s worth measuring the tow ball diameter first — if it’s 50 mm (2″), this cap should sit snug. The product is compact and weighs approximately 40 g. For reference, the model number is LQUK0003334 and the brand is Uposao.
All told, it’s a no-nonsense little protector: quick to fit, keeps rust and dirt at bay, and a neat, inexpensive way to look after your towing kit. Pop it on and you’re sorted until the next tow.
