Question:

Is this rated for 21,000 lbs since it is listed for the 3” stow and go?

Hello Jack,

Great question! B&W does not have a specific weight rating for the Trailer Hitch Receiver Lock for 3" Hitches - Flush - 3-1/8" Span - Stainless Steel # BW23FR, they have it on their site that it works for Class III, IV, and V hitches. As you can see from the chart that I attached the Class V is listed for up to 25,000 pounds. With that being said, yes it will work great with the 21K Tow & Stow.

Hey Jack, did the hitch lock end up working well with your 21K Tow & Stow setup? Knowing how it handled that load could help others looking at the same combo.
