Black Friday Doorbuster Yakattack 13x13 Shortstak Upgrade Kit For Blackpak Pro - Battleship Grey Guaranteed [yCnWT2F6]

The ShortStak Upgrade Kit is 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.

 

The design of the ShortStak inherits many of the same features found on the BlackPak Pro. From lightweight injection molded parts and tongue and groove assembly, to the GridLoc mounting platform found inside and outside the crate, making it obvious they were made for each other. An addition of heavy-duty hinges and support straps were critical to restrict any overtravel of the larger top compartment to prevent damage to your BlackPak. Overall, the length and width dimensions of the ShortStak will match the corresponding BlackPak. The interior depth of the ShortStak will be 4.25 inches across all three sizes.
