This style of coupling, usually suited to a 50mm Australian Standard tow ball, is suitable to be used where either there are no brakes fitted to the trailer or the braking system does not require activation from a sliding or overrun coupling.
AL-KO couplings are simple to attach to the towball and provide safe secure attachment of the trailer to the tow vehicle.
