Stop carrying a bag of hitch balls and a torque wrench to every job. The B&W TS10049B Tri-Ball Mount puts a 1-7/8 inch, a 2 inch, and a 2-5/16 inch ball on a single Class IV receiver shank. Flip the mount to the ball size your trailer needs and you are done. Built by B&W Hitches in Humboldt, Kansas -- the same company that supplies OEM towing hardware to major truck manufacturers -- this platform is forged and heat-treated for long-term durability under real towing loads.
Whether you are hooking up a small utility trailer, a mid-size travel trailer, or a heavy fifth-wheel-class bumper-pull, the TS10049B has the ball size you need already mounted and torqued. The three-ball layout eliminates the most common cause of a delayed departure: realizing the ball on the hitch is the wrong size for the trailer sitting in your driveway.
B&W designed the Tri-Ball series for working farms, fleet operators, and serious RV owners who tow multiple trailers with different coupler sizes. The platform is zinc-plated for corrosion resistance, and each ball is properly heat-treated chrome steel rated to handle the loads its coupler class demands.
1-7/8", 2", and 2-5/16" balls are installed at the factory -- no additional hardware needed to cover the three most common coupler sizes in North America.
Engineered for Class IV receiver hitches, supporting the gross trailer weight and tongue weight ratings appropriate for heavy-duty bumper-pull applications.
B&W uses forged steel with heat treatment on the shank and ball platform -- not stamped or cast components -- for consistent strength across the part.
Zinc plating resists road salt, moisture, and UV degradation, keeping the mount serviceable through multiple towing seasons without significant surface rust.
If you are new to multi-trailer towing or recently added a rig to your fleet, here is a quick coupler-to-ball reference:
The TS10049B is designed for standard 2 inch square Class IV receiver tubes. Before ordering, confirm your hitch receiver opening is 2 inches square -- Class IV hitches on full-size trucks and SUVs almost universally use this opening. Class I and Class II hitches with 1-1/4 inch receivers are not compatible.
The platform is designed as a ball mount rather than a drop/rise adjustable shank, so verify that your vehicle's receiver height relative to your trailer coupler height is within the range this fixed-drop mount provides. For applications requiring significant drop or rise adjustment, B&W also offers adjustable-shank Tri-Ball variants.
Installation is straightforward -- no drilling, welding, or wiring required:
