The CURT vertical trailer hitch adapter is designed to turn a vertical receiver into a standard ball mount platform or horizontal receiver tube. A trailer hitch with a receiver tube that points down toward the ground is sometimes preferred on a vehicle because the hitch is then able to be completely hidden from view. With this design, a special ball mount with a vertical shank is required to all make the vehicle ready for towing a trailer or hitch-mounted accessory. This CURT vertical receiver adapter comes with a 2 x 2 shank and features a gross trailer weight capacity of 4,000 lbs. and a tongue weight capacity of 400 lbs. It has a length of 9-1/8 and a drop of 2-1/4. CURT adapters are constructed using our quality manufacturing processes. We CNC-form each unit, weld it together using advanced robotic systems and then mechanically descale every surface to make each adapter smooth to accept a finishing coat. Our adapters receive a durable gloss black powder coat finish to give them excellent rust, chip and UV resistance.
