What ball size does this coupler take?

It fits a 2-inch ball only. A 1-7/8-inch or 2-5/16-inch ball will not latch correctly.

Can I bolt it on instead of welding?

No. It is a weld-on coupler and has no bolt holes. It needs to be welded to the trailer tongue.

What trailers does the 50-degree angle fit?

It is made for A-frame tongues where the two frame rails meet at a 50-degree angle. Measure your tongue angle before buying.

Is 5,000 lb enough for my trailer?

It covers most single-axle utility, boat and small equipment trailers. Stay under 5,000 lb gross trailer weight, including the load and the trailer itself.

Does it come with a latch pin or lock?

No. The flat-lock latch is built in, but a safety pin or coupler lock is sold separately.

Our take on the HUSKY TOWING 87079 Class III Trailer Coupler

The Husky Towing 87079 is a weld-on A-frame coupler for trailers with 50-degree angled frames. It takes a 2-inch ball and is rated to 5,000 lb gross trailer weight, putting it in Class III territory for utility, boat and small equipment trailers. The flat-lock latch and black powder coat are its main selling points against generic couplers. It is a bare weld-on part, so it suits people building or repairing a trailer rather than anyone wanting a bolt-on swap.
