Fulton Fas-Lok Class II Trailer Coupler – 2" Ball, 3,500 lb (222500101)
A reliable, American-made Class II trailer coupler for straight-tongue trailer frames. The Fulton Fas-Lok 222500101 accepts a standard 2" hitch ball and is rated to 3,500 lb gross vehicle weight — covering the majority of boat and utility trailer applications. The heavy-duty safety latch prevents accidental uncoupling while in transit, and a padlock hole lets you add a lock for theft deterrence when the trailer is parked. The ball clamp assembly is factory-adjusted to the ball size and is field-serviceable, so worn components can be replaced without swapping the entire coupler. Zinc finish for corrosion resistance. Meets or exceeds SAE standard J684.

- For lighter trailers, see the Fulton 1-7/8" Ball Coupler, 2,000 lb

Parts Desk Insights
Best used when replacing a worn or damaged coupler on a straight-tongue trailer frame rated to Class II / 3,500 lb. The key buying decision between this (222500101) and the 222000101 is the frame channel width — confirm your trailer’s tongue channel dimensions before ordering, as both share the same ball size and capacity. The field-serviceable ball clamp is a practical advantage: if the clamp wears over time, you replace just that component rather than the whole coupler. The padlock hole is a useful built-in feature; pair it with a coupler lock for added security when the trailer is stored unattended. For a 3" channel frame, the Fulton 223000101 is the right choice.
