Following the release of the reimagined BlackPak Pro, it has been clear that for many anglers, bigger is better. With that concept in mind, our design team began working on solutions to increase the usable space, inside and outside, of the BlackPak Pro. The resulting product does all of that, and will come in three different sizes to fit all three BlackPak Pro models. Please note, this is not a stand-alone box and requires the use of a BlackPak Pro. Fit & Design: A stackable box that replaces the lid of a new or existing BlackPak Pro, giving you a second layer of storage for quick access go-to items Its construction is virtually the same as the BlackPak Pro, however, it is only about 40% of the original height The bottom edge of the ShortStak side panels is angled to match the geometry of the BlackPak opening, giving you the same water-shedding fit as the original lid More space for more gear Lightweight injection molded parts Heavy-duty hinges and support straps Rubberized lid bumpers Includes stainless steel hardware Additional Details: Included in the ShortStak Upgrade Kit, you will receive four ShortStak Side Panels, one Bottom Panel, four rubber ShortStak Bumpers, one pair of hinges, one pair of ShortStak Catches, one pair of Latches, one pair of straps, and all of the stainless steel hardware needed for the assembly. As an upgrade kit for the BlackPak Pro, the ShortStak does not include a lid Requires components from a 13x16 BlackPak Pro Build for use in harsh marine conditions Built for Life Guarantee
