The Venta-Lite Large Side Tray from PRESTON manages the NEW open clamp knuckles which are incredibly easy to use and provide a super strong grip against the box leg. In combination with our included inserts, you can use our OffBox 36 side bins on ANY seatbox leg diameter. So it doesn't matter which seat box leg you use, you can use our OffBox 36 seat box accessories. The Offbox Venta-lite Large Side Tray with two knuckles is the perfect size for most situations, with a capacity of 6 3 pint bait boxes with some extra space. The mesh promotes airflow which in turn keeps your bait cool while reducing weight.
