Mounts have a unique locking mechanism which allows the unit to slide along the track and easily secure it in position by tightening the two knobs located at the front of the unit. These knobs are held on place with spring washers so that the vibrations of the boat do not allow anything to vibrate loose. We also provide two synthetic levelers at the end of the unit to give the mount added support. Capable of mounting a downrigger, single rod holders, Sure-Stop Track, as well as double, triple, or quad cross-plates.
