Secure, quick access, and versatility were the foundational requirements when designing the TracPak. Mount one or two storage boxes on a MightyMount or GearTrac and 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 to maximize compatibility. The Quick Release Base can also be surface mounted using the included stainless steel screws on the BlackPak Pro, the deck of your kayak, or other flat surfaces. Each storage box is water-tight and features an eyelet if you choose to use a leash for added security. For enhanced organization, four white adhesive labels are included to identify the contents inside each box. Made from marine-grade polymers and built in the USA.
