Manfrotto 057 Magnesium Ball Head with MSQ6PL Quick Release Plate

This 057 Magnesium Ball Head from Manfrotto features an integrated Arca-type clamp and a MSQ6PL Quick Release Plate. Arca-type compatible quick release plates can be attached or removed from the clamp by tightening or loosening the clamp's locking knob. Within the recessed surface between the clamp's jaws is a retaining pin, which prevents an installed quick release plate from accidentally sliding off when the clamp is opened.
