The YakAttack Gear Trac 4 Inch Accessory Mounting Track allows for versatile mounting of all your paddling and fishing gear. Gear Trac features a T-slot running from end to end allowing for the use of any Mighty Mount accessory to be easily installed and removed. The concave shaped base of the track allows for a solid mount to flat surfaces as well as surfaces with some contour. While the Gear Trac can be installed to almost any kayak it can also be used as an articulating platform when used with the Mighty Mount or Pan Fish Portrait mounts. The possibilities are almost endless. Includes drill bit for installation.
