Looking for suggestions on a utility tray that you can adjust compartment sizes big enough to fit spinner baits. I know they make spinner bait specific but i don't own enough to justify that, plus i want the utility tray size to fit with my other 3 trays in my milk crate for kayak fishing. Thanks folks. 

Plano has this 3600 size utility box that has an open side that fits spinner baits just fine if you are only going to carry a few at a time.

Put them in a worm binder.   They stay untangled from any other spinnerbaits  and take up less room than a box. 

 

Gamakatsus are basically universal in their configurations.

Thanks for the suggestions, ill check them out!

Soft sided CD cases work, too!

Any deep Plano box has worked for spinnerbaits for me.
