A receiver hitch is a type of towing accessory attached to the rear of a vehicle, designed to facilitate the connection of trailers and other towing equipment. It typically consists of a square tube that allows for the insertion of various attachments, such as ball mounts or cargo carriers, making it versatile for different towing needs. Receiver hitches come in various classes, each rated for different weight capacities. The class of a hitch determines how much weight it can safely tow, ranging from light-duty options for small trailers to heavy-duty hitches for larger loads. Proper installation and usage are essential for safe towing.
