Trojan Coupling V2 2500KG DuoFit 50mm-1 7/8"
Easy to install, easy to retro-fit, used by OE manufacturers. No confusion with the respective towball sizes, fits 50mm and 1 7/8th easily, without the need to swap the handle.
The new Trojan duofit coupling negates the need for the operator to change over the handle. The coupling simply automatically fits to the size of the towball.
