Kessler Half ball for leveling video heads on tripods with 100mm bowl. Adapts flat-base video heads for tripods with 100mm bowl. Will also allow for mounting to a 75mm bowl tripod, as well.
With its 100mm levelable ball, the Ball Mount can be mounted to tripod legs with a 100mm bowl.
With its 75mm fixed ring mount, the Ball Mount can be mounted to tripod legs with a 75mm bowl. The leveling will need to be done with the tripod legs. The reason being is that a 75mm ball/bowl system does not have enough surface area to accommodate the clamping force of heavier rigs such as a slider.
The K-Pod™ does not come with a 100mm ball, and is needed for use with heads other than the Kessler "Hercules" Head, if they do not have a 100mm ball.
