The Plano Line Spool Leader box is perfect for keeping your small spools in check. The rubber grommet holds the line as it comes out of the spool so you don&';t have to search for the end. The latch keeps it nice and tight so all your spools are in one spot. We like to mark on the outside of the box what line is in what spot using a label maker or sharpie. We&';re sorry but an oversized shipping fee will apply at checkout.
