All aluminum construction and unrivalled in stability, the 475B Pro Geared Tripod incorporates a unique center brace structure system, reliable quick-action leg locks, non-rollback three faceted center column, spirit level and rubber/metal spiked feet. The revolutionary center brace system can be operated in a symmetric or asymmetric way. This allows you to achieve two important results: fast positioning by locking the braces so that all of the legs will spread to the same angle and open instantly, or individual setting of the angle of each leg for the ultimate in tripod flexibility. To avoid annoying delays in leveling the tripod, the telescopic center braces have been designed with two ''click stop'' positions that allow you to easily find the same spread angle on all three legs. The second improvement has been made to the leg locking system. Anti-rotation tubing and leg collars make for a tripod (or monopod) that's easier and faster to open, position and close. Manfrotto uses several different types of anti-rotation system - on Magfiber and Digi series tripods, the elliptical or three-faceted shape of the concentric tubes means they cannot rotate, while on round-tubed tripods, small protrusions down the length of the tube keep sections perfectly aligned.
