The GN7 Square Straight Gooseneck Coupler Adapter for Semi-Tractors are deigned for trailers with a 4" ID square tube. Pull your gooseneck trailer with a semi-tractor or pickup mounted fifth wheel. Simply replace the coupler with a king pin. Easily switch back and forth. The 2″ SAE king pins are the industry standard and are suitable for use in all over-the-road applications. PopUp Hitch's part measures 4" outside to outside. Make sure it will fit as many of the China made tubes are not all sized consistently and many are under sized.
