Secure, quick access, and versatility were the foundational requirements when designing the TracPak. They 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. The TracPak features a quick release track base compatible with all YakAttack MightyMounts, GearTrac, and most other factory-installed kayak track. When attached to a track, the Quick Release base features an array of slots, allowing for micro-adjustments in each direction of the t-bolt. This should maximize compatibility by increasing the locations where the TrackPak will fit on your watercraft. If you would rather surface mount the quick release base, included are stainless steel screws for attachment on the BlackPak Pro, the deck of your kayak, or other flat surfaces. For surface mounting on anything other than the BlackPak Pro, a 1/8 in. drill bit will be required for the installation. Please use a handheld screwdriver and ensure not to overtighten the stainless screws.
