Query: Doesn't fit my 3/8" square spit rod

I wanted these for my Weber Summit gas grill to cook smaller items on the rotisserie since it has four closely spaced prongs while the forks that came with my grill have two prongs that are farther apart. The description says that these fit a 3/8" spit rod, which I thought would be perfect for the rod that came with my grill which is 3/8" square. They don't say in the description that they meant a 3/8" round spit rod. Therefore, these don't fit the rod in the Summit grill. I'm going to try to grind out the hole with a rotary tool, but then will lose the finish in four spots which will result in it rusting at those points. My complaint is why don't any of these products (not just rotisserie accessories,) specify what they fit in both size and shape?
