The TowSmart Trailer Hitch Receiver Tube is commonly used to extend the length of your existing receiver and welds on for a custom towing application. Designed for weld-on installation, it features a built-in collar for superior strength. It accepts most 2 In. x 2 In. ball mounts and other hitch accessories, and features a pre-drilled pin hole that accepts locking or non-locking hitch pins. Made of durable, heavy-duty steel construction with a black powder coat finish that is corrosion-resistant to withstand extreme weather. It is important that you know the total weight of the trailer and its contents, and that you do not exceed the recommended maximum towing capacity determined by your vehicle manufacturer.
