Description

The WINTERHOFF WW 350-RB is a coupling head for trailers with a round drawbar, fitted with cross bolting. The coupling connects the trailer to the tow ball of the towing vehicle.

The variants differ in their bores: the code 1212 stands for bores for M12, 1414 for bores for M14. The bore diameter should therefore be measured on the drawbar. With a high drawbar weight, the permitted nose weight of the coupling is the decisive value, not the permitted gross weight. New bolts and self-locking nuts should be used for fitting and tightened to the torque specified by the manufacturer.
