The TracPak quick release base provides the foundation to mount one or two TrackPak stackable storage boxes onto a single mounting point. This mount is compatible with all YakAttack MightyMounts, GearTrac, and most other factory-installed kayak accessory tracks. 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 install. Please use a handheld screwdriver and make sure to not overtighten the stainless screws. Made from marine grade polymers the TracPak is designed for use in harsh marine conditions.
