AB Tools 3.5 tonne 50mm tow ball and 25mm pin flange coupling – silver
This is a proper, no-nonsense tow ball and pin coupling built for day-in, day-out towing on vans, 4x4s and commercial vehicles. If hauling trailers, horseboxes or work kit is part of your routine, this gives a reassuringly solid connection — sensible specs, nothing flashy, just kit that does the job.
Built for real use
The 50mm ball is the go-to size for heavier trailers and with a maximum capacity of 3.5 tonne (3500 kg) this unit copes with the tougher jobs. The 25mm pin suits standard flange towbar setups and comes with tags to stop pins working loose or getting misplaced — a small detail that saves a lot of faff on the road.
Key benefits and what it fixes
- Reliable towing capacity: rated to 3.5 tonne, so it’s suitable for most van and 4×4 towing where lighter balls just won’t cut it.
- Corrosion resistance: silver powder-coated finish helps keep rust at bay — handy if the trailer only comes out in winter or lives outside.
- Quick fitting: pre-drilled mounting holes (2 x M16, 16mm) with 90mm centres make fitting straightforward — remember fixings are not included.
- Secure pins: fitted tags reduce the chance of pins vibrating loose or going missing during a trip.
- Approved and tested: ECE R55 approved with a D-value of 17.2 kN and a maximum static load on the ball of 200 kg — the sort of numbers you’ll want if you’re sticking to regs and towing safely.

Some practical tips: always check both vehicle and trailer ratings before you hook up so nothing’s being pushed past its limits. Use suitable M16 bolts and locking washers when fitting, and give the coupling a once-over if the vehicle spends time near the coast or in salted winter conditions — the powder coat helps, but a little attention extends its life.
Overall, this tow ball and pin flange coupling is a solid, regulation-friendly choice when you need a dependable flange-mounted setup. No faff, no gimmicks — just a straightforward, robust solution to get your trailer hooked up and keep it there.
