The CB-38 FTR Ball Head with QRP-50 Quick Release System from FLM is an aluminum alloy ball head that can support 55.1 lb. It has three locking knobs; one controls 360° panning and one controls the amount of friction and movement of the ball. The third knob controls FLM's patented tilt function. When the tilt function is activated, the ball moves along a straight line and acts as a tilt head. When the function is deactivated, you have full control over the movement of the ball in all directions.
