The CURT 45810 multi-use ball mount is able to carry a bike rack in addition to towing a trailer, providing added convenience and streamlining the towing process. It has a 2 inch receiver and a 2 inch drop, with a GTW of 7,500 pounds and a tongue weight of 750 pounds. The black powder coat finish protects the ball mount from rust and other corrosive elements. The seams are robotically welded to ensure extra durability. Note that the receiver section is not intended to be used for towing. It is specifically intended for use in supporting a bike rack.
When trying to decide what drop or rise length is needed, you need to consider the distance from the ground to the bottom of the trailer coupler and from the ground to the top of the inside of the receiver. Keep in mind the gross trailer weight (GTW) includes the weight of the towing trailer in addition to whatever the trailer is carrying. Tongue weight refers to the force that the coupler puts on the trailer ball. The total weight that can safely be pulled depends whether a weight distribution system is present. A weight distribution system spreads the cargo weight throughout the trailer so it balanced evenly. Ball mounts such as the 45810 are mounted inside the receiver tube and need to be securely installed. Always make sure the trailer is properly hitched before towing, to avoid unnecessary accidents.
