Except mine is 28.5in wide......![]()
I'd still lump it into the 26/27" wide class of boxes. Possibly 29". What are the dimensions inside the top lip? As in what is the widest box you could set on the top recess? Tool boxes usually get lumped into a standard sizing of ~20, 22, 26/27, 28/29, 32-34, so on and so forth. They may vary a bit depending on specific box, but usually they fit into one of those groups.
