Has a unique locking mechanism which allows the unit to slide along the boat's ingegrated angled track system and easily secure it in position by tightening the two knobs located at the front of the unit. These knobs are held in place with spring washers so that the vibrations of the boat do not allow anything to vibrate loose. Two synthetic levelers at the end of the unit to give the mount added support are also provided. Top mounting surface is 3" x 4". Mount a track to multiple mounts (2 for 12"-18" tracks, 3 for 24"-48" tracks, 4 for 60"-72" tracks) for holding components
