The Flat Base Adapter for 75/100mm Bowl Tripods from Libec is designed to adapt flat base tripod heads to fit tripods and hi-hats with 75 or 100mm bowls, allowing you to gain the quick leveling advantage of bowl tripod legs with your flat base head. It features a stepped shape that lets you mount the adapter on tripod legs, and you can mount a flat base head with either a 1/4"-20 or 3/8"-16 threaded mounting hole. A tightening knuckle is included to secure the adapter to your legs. In addition to flat base tripod heads, the adapter can also be used to attach other accessories that have either 1/4"-20 or 3/8"-16 female threads, such as a slider, to 100mm bowls.
