Maypole black PVC towball cover with red reflector – fits 50 mm flange towballs
Keep your towball clean and visible
This MP139 towball cover is a proper, no-nonsense bit of kit that stops muck, rain and road grit turning your towball into a rusty lump. If your towball sits on the back of the car for days between trips, a cover like this saves time and faff when you want to hitch up again. The built-in red reflector adds a bit of extra visibility once it’s fitted – handy on dark nights or when you’ve parked on the street.
Key benefits and typical uses
- Protects the towball from corrosion and knocks, so there’s less cleaning and less chance of damage when you store the car or trailer.
- Perfect for everyday use: commuting cars, weekend trailers and caravans that use flange-style 50 mm towballs (see compatibility notes below).
- Easy to fit and remove — no tools, no messing; just pop it on when you’re not towing.
- The reflector helps other road users spot the towball more easily once it’s in place — a small safety bonus in poor light.
Practical details and compatibility
Some useful technical bits: the cover is made from black PVC, model MP139, designed specifically for flange-style 50 mm towballs. Dimensions are neat and compact (approx. 3.46 x 4.25 x 8.58 cm) and it weighs around 130 g, so it won’t take up much room in the boot or a storage compartment. Manufacturer part number: MP139 (OEM 139).
Important compatibility notes — don’t skip these: this cover is not suitable for swan-neck towbars, detachable towbars or for certain AL-KO towball setups used on some caravans. If you’re unsure, check the shape of your towball first — flange-style 50 mm is the one that fits.
Little things that make life easier
- No more scraping crusted mud off the towball before a trip — save time and keep your hands clean.
- Small and compact enough to stow in the boot or a locker when not in use.
- An inexpensive bit of protection that stops small issues turning into costly jobs later on.
If you’re unsure about fit, take a quick look at the towball on the car or trailer — this cover is aimed at standard flange 50 mm types. It won’t fix every towing niggle, but it will keep the bit you hitch up with in much better nick, and that’s a proper bonus in the long run.
