The Kupo KS-236 trailer hitch adapter for 2″ tubes is machined from a solid block of aluminum with a black anodized finish. The Kupo hitch adapter measures 5 x 5 x 48 cm and allows additional car equipment to be securely mounted on any vehicle equipped with a 2″ hitch. Two 1/2″-13 bolts and nuts instead of the traditional hitch pin ensure a strong, reliable connection with no wobble. Two black pin couplers are included that can be attached securely to the 3/8″-16 hex screw adapter to effortlessly connect any 2″ pipe. The eight holes around the 3/8″-16 female thread allow the angle of the coupler to be adjusted to 45 degrees. The other eight 3/8″ – 16 female threaded holes are arranged in a row on either side and allow you to connect any rigging equipment equipped with 3/8″ – 16 male threads.
