RAM Mounts Track Ball with Side Track Base

The Track Ball Side Track Base consists of a t-bolt, ratchet tooth and groove composition and 1.5" rubber ball. With a turn of the knob you can quickly fasten, adjust or remove the base to your existing track system. The ratchet tooth and groove composition enables you to slide and relocate the mount along the track; it can also rotate 360 degrees around, parallel to the track. The patented rubber ball design creates friction; this stabilizing the entire mount, along with dampening shock and vibration.
