Purchased 12 of these and they came perfect condition, 2 days ahead of schedule and in ultra-heavy duty packaging to avoid shipping damage. I had no issues using 2x4 bunk boards although they are for 6" and 8" wide bunks. The brackets were used to convert my dual pontoon to a Tritoon trailer. And if you are like me and don't frequently check for loose bolts, I would strongly suggest using with Leaf Spring Shackles to reinforce bracket base.
