Description
Overview:
This lock barrel and safety ball set (MPN 763 770) is designed for AL-KO AK301 and AK351 towing heads used on heavy-duty trailers and plant transport. The set provides a simple security measure at the coupling: the replacement lock barrel secures the hitch mechanism on the head, while the safety ball occupies the ball cavity when the trailer is uncoupled to deter unauthorised hitching. The safety ball is sized to suit standard 50 mm (1.97 in) towball couplings. Built for workshop and fleet environments, it is a practical service part where AL-KO AK301/AK351 hitch heads are fitted across flatbeds, plant trailers and other commercial trailers. It is intended as a direct-fit service item for the specified AL-KO coupling heads, helping keep assets secure when parked or stored.
