Sold as a two pack, these trays are a simple way to "Make It Yours" and customize your TracPak Stackable Storage Box so it fits your specific needs. From tools to tackle and anything in between, these trays provide heighten organization, making your time in the outdoors more efficient. The trays are half depth meaning they only take up half the height of the internal space of the TracPak, so a single TracPak can hold up to two trays. Included are ten Stacking Tabs. When used these Stacking Tabs create the ability for a single tray to be suspended within the TracPak leaving the bottom open for miscellaneous storage of larger items. When the TracPak is closed a suspended half-depth tray comes in contact with the underside of the lid keeping items secure in each compartment of the tray. If you are using two half-depth trays inside a single TracPak then the Stacking Tabs are not necessary. Made from marine-grade polymers, the TracPak is designed for use in harsh marine conditions. It is made in the USA and backed by our Built for Life Guarantee.
