The YakAttack TracPak Track Mount, aka The TracPak Quick Release Base (mount only), is a highly versatile mount with a sturdy foundation for attaching one or two TrackPak Stackable Storage Boxes. This mount is compatible with all YakAttack MightyMounts, GearTrac, and most other factory-installed kayak accessory tracks, making it suitable for a wide range of watercraft. When attached to a track, the Quick Release Base offers a range of slots, allowing micro-adjustments in each direction of the t-bolt. This maximizes compatibility by increasing the locations where the TrackPak can be mounted on your kayak.If you prefer to surface mount the quick-release base, use the included stainless steel screws for attachment on the BlackPak Pro, the deck of your kayak, or other flat surfaces. However, for surface mounting on anything other than the BlackPak Pro, a 1/8" drill bit will be required for the installation. To ensure a secure fit, please use a handheld screwdriver and make sure not to overtighten the stainless screws. The TracPak is constructed from marine-grade polymers, which make it highly durable and capable of withstanding harsh marine conditions.Compatible with the TracPak Stackable Storage BoxIncludes Quick Release Base, t-bolt, knob, and surface-mounting hardwareProduct Dimensions: 8 13/16 x 4 1/16 x 1 9/16 in.Part #: SSO-1004Quantity per pack: 1Manufacturer's lifetime warranty
