The compact Coconut Half-Ball 75mm Bowl Head is a 75mm half-ball adapter that allows you to use select flat base tripod heads on legs with a 75mm bowl. The durable aluminum bowl features a 75mm diameter, a 3/8"-16 head mounting screw in the center, and a bubble level extended on the side.
The head can be quickly adjusted using the quick release lever, and the positioning and tightness can be fine-tuned using the locking collar. It can support camera rigs weighing up to 44 lb. Included set screws help secure your head on the adapter and prevent it from slipping.
