Jim, I use Falcon FTO boxes which are narrower on certain models; I removed one or more of the dividers in the tackle-trays to get my boxes to line up. The dividers are glued in, and will come out pretty easily with a little “encouragement”. Push to the left or right and they will evidentually break fee at the top and bottom, You can then push them back and forth until the glue on the bottom of the divider lets go. This allows you to retain the tray bottom and strap. I have had as many as 7-9 FTOs in one tray. I have re-gluded them when I have sold boats in the past and they have worked well when re-installed… Good luck, Gary Hollander
