This unique organizer has 12 removable bins that can either be individually opened from within the organizer unit or be taken out for full accessibility on the jobsite. A lock on top securely holds all of the bins in place, and allows items to be safely transported. This organizer can be stacked with other organizers from the PRO line or with another similar unit for optimal access to all your small parts and accessories. | DEWALT Flip-Bin Organizer DWST14121
