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 a track base compatible with RAM® Tough-Track™ as well as most third-party track systems. Each RAM® Universal 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. The RAM® Universal Adapt-A-Post™ Track Base also contains a locking lever used to prevent the base from spinning loose with any rod holder movement. Conversely, you can adjust the position of the base along the track by lifting the lever, loosening the base and reposition without loosening the rod holder.
