The TowSmart Receiver Adapter is commonly used to convert your 2 ½ inch receiver opening into a 2 inch receiver opening. This adapter allows you to use 2 inch hitch mounted accessories with a 2 ½ inch hitch receiver. Ideal for bike racks, cargo carriers and other trailer accessories. The heavy-duty steel construction is extremely durable with a black powder coat finish that is corrosion resistant and provides superior protection from the outdoor elements. Using this adapter will reduce your tongue weight capacity of your hitch by 50 percent. Do not use this hitch adapter in towing applications.
