The RAM Universal Adapt-A-Post Base is the revolutionary answer to combine compatibilty across post and spline systems from RAM Mounts, Scotty, Fish-On, Railblaza, Cannon, Brocraft, Cabela's and Bass Pro Shops. This version of the RAM Universal Adapt-A-Post is designed specifically to replace the existing post and spline base attached to the Hobie H-Rail Mount. Simply take out the security pin attaching the existing post and spline base from the Hobie H-Rail Mount and install the RAM Universal Adapt-A-Post Hobie H-Rail Mount Conversion Kit. Each RAM Unviersal Adapt-A-Post features a quick-release button to safely disengage the rod holder as well as keep it secure while fishing out on the water.
