Manufacturer's Description: The RAM Track-Node is a ratcheting, highly adjustable track base designed to accommodate both fishing rod holders and the RAM Tough-Pole action camera mount. This kit includes the RAM Track-Node base, RAM ROD® ratchet attachment, 8” extension arm, and RAM ROD 2000 fishing rod holder. To prevent any side-to-side movement on the track, a fixed washer is included so the RAM® Track-Node™ base can be securely tightened. With a quick twist of the knob, easily swing the RAM ROD 2000 rod holder in and out of your vessel. To install, simply slide the RAM Track-Node base into your track mount system thanks to the connected T-Bolt and turn the circular knob to tighten in place. Loosen the circular knob for 360-degree rotation. The RAM Track-Node is compatible with all versions of the RAM Tough-Track and most third-party track mount systems.
