Secure, quick access, and versatility were the foundational requirements when designing the TracPak. We wanted the ability to mount one or two storage boxes on a MightyMount or GearTrac, and with the TracPak, you can stack two boxes onto a single mounting point, helping save track space for other accessories. Please note this is only the TrackPak Spare Box and the Quick Release Base is sold separately or all together as part of our two-pack combo kit.The stackable storage boxes quickly and securely snap onto the base (sold separately) and on top of each other. When two boxes are stacked on top of each other, you have the ability to not only access the top box, but you can access the bottom box. With interior dimensions measuring 8.375 x 5.375 x 2.375, there are many ways to utilize this secure quick access storage box. From tools to terminal tackle, the TracPack is a unique and handy storage solution for both recreational and kayak anglers. The TracPak is not waterproof or water-tight and does not float, so each storage box features an eyelet if you choose to use a leash for added security. For enhanced organization, included are four white labels. These adhesive labels are designed to fit on the latch of the box and create an area to identify the contents inside using a permanent marker like a Sharpie. Additional TrackPak boxes and the quick release base are also sold separately.When used with the optional TrackPak Quick Release Base you have the ability to attach the system to any YakAttack MightyMounts, GearTrac and most other factory-installed kayak track. If you would rather surface mount the quick release base, included with the Quick Release Base are stainless steel screws for attachment on the BlackPak Pro, the deck of your kayak, or other flat surfaces. 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.Includes assembled spare box with lid and four white labels onlyQuick Release Base sold separately or all together with the TacPak Combo KitIndividual Storage Box Weight: 1 lbs.Internal dims: 8.375 x 5.375 x 2.375External dims: 9.5 x 6.5 x 3.625Made in the USACovered by our Built for Life GuaranteeSKU: SSO-1003UPC: 819731015197
