Flange towbars: the versatile, accessory-friendly option
Reviewed by an experienced Leicester towbar fitter Last updated
A flange towbar has a 50mm ball bolted onto a flat plate, which makes it the most versatile and accessory-friendly ball style: you can adjust the height with drop plates and add bumper protectors, twin sockets and most bike racks. It is also the cheapest option. Flange is a ball-style choice; the alternative is swan-neck, and you separately choose fixed or detachable.
Why choose a flange towbar?
- Height adjustable: drop plates and different bolt positions let you match the trailer height, which matters for level towing
- Accessory-friendly: works with bumper protector plates, height-adjustable towballs, twin electrics brackets and most bike racks
- Value: generally the most affordable ball style
- Robust: a favourite for trailer, trade and agricultural use

The AL-KO stabiliser point
Fitter's tip
A flange towbar can be used with an AL-KO stabiliser, but you have to check clearance: a bumper protector plate or tow step bolted behind the ball can foul the stabiliser. Caravanners who run a stabiliser often prefer swan-neck for that reason, while flange wins if you need drop plates and accessories.
Who flange towbars suit
Budget-conscious buyers, anyone needing height adjustment, trailer and commercial users, and drivers who run several towing accessories. See the cost guide for prices.
