The Manfrotto MSQ6 Quick Release Plate is designed for use with Manfrotto's Arca-compatible Q6 Top Lock quick release system and is designed to offer photographers a fast, easy to use and secure quick release mechanism suitable for heavy pro camera equipment.
The plate has a redesigned screw, which can be tightened to your camera in a number of different ways: by hand, using the special flip-handle; using a coin, inserted into the wide slot; or with the supplied allen key for maximum stability.
The plate is also compatible with Arca-style systems from other manufacturers.
