DAKA Bins are designed to keep loose parts, gear, ammo, and other items secure inside our own Hard Cases or any case outfitted with the Magpul DAKA GRID Organizer. With each peg on the underside of the Bin fitting securely into the GRID Panels to positively locate them in any position, we also made them stackable and functional outside of your DAKA GRID equipped case so they're equally at home on your workbench or wherever else you'd like to use them.
