The Leofoto YB-75C Series Leveling Bases are designed to help users level a tripod in order to maintain level horizons and reduce time-consuming post processing corrections. The leveling base features a lightweight aluminum construction and the base is topped by the widely used Arca-type clamp. What differentiates the YB-75C from the YB-75K line is that the C uses a lever-release clamp while the K uses knob release clamp. The handle twists to lock the base in place for ease of use when mounted with three different handle length options available.
