I assume you're referring to plastic organizer boxes, not to toolboxes that have built-in trays. The terminology isn't clear when doing searches. And I assume you want dimensions. The standard sizes seem to be set by Plano -- whose website has very little besides pictures. Some retailers' product descriptions have dimensions. 3400 - 8.25" x 4.25" 1.38" 3500 - 9.13" x 5" x 1.25" 3600 - 10.75" x 7.25" x 1.75" 3700 - 14" x 9.13" x 2" If you get a backpack or bag designed for tackleboxes, it will probably be sized for the 3600. Bass boat storage compartments might be different. You need to do some pre-shopping. There are a lot of variations, depending on latches, handles, and depth. For example, I think Plano's Edge series is thinner. And those the only sizes. You might be better off waiting until you get your boat, measuring the compartments, and then going to WalMart to see what fits.
