    This coupler’s pretty good and I’d totally suggest you giving it a try. I’ve been using it as a replacement on my utility trailer and it’s doing great!

    Installed it without any trouble, even welded it myself. Fits the ball perfectly – and it even comes with an adjustment nut in case you need a better fit for locking it down.

  3. AC

    I make a lot of trailers and honestly, this coupler is just as solid as any other one you’d get for the same price, or even more expensive ones. Plus, I’m a fan of the two extra holes – they’re great for sticking a plug weld in and making sure it’s super secure.

  4. WM

    Just add a good weld and bolt for some extra strength – they’ll fit perfectly.

    Slapped this on my harbor freight trailer. Did the job pretty well. I only used grade eight hardware, by the way.
