The key feature of the Manfrotto MT055XPRO3 is its 90 Degree Centre column mechanism, which allows the column to be extended vertically as normal, or horizontally. The horizontal column mechanism is housed within the tripod's top casting for compactness, but it is easily and quickly extended whenever you need it. Switching between vertical and horizontal column orientation requires no disassembly, and can even be done with a camera attached. .The legs of the 055XPRO3 tripod are also fast to extend and adjust, thanks to the Quick Power Lock levers. The special design of the QPL levers allows single-handed opening of all leg sections in one action. Intuitive and ergonomic leg angle selectors allow each leg to be independently and solidly set to any of the preset angles, again allowing considerable positioning freedom. A bubble level is built in to the top of the Centre column for precise framing. The bubble level rotates freely around the Centre column, so it can be positioned wherever it's easiest for you to see tithe X-PRO 3-Way Head has retractable levers which make it ultra-compact, and also features new friction controls on the portrait and tilt axes, to help balance the weight of camera equipment so that fine framing adjustments can be made with the locking knobs open, only locking everything down once the shot is ready. .SPECIFICATIONS attaches by. 3/8 attachment type center column rapid closed length 29.13 in Color black color column cross section three-faceted column tube diameter 28mm leg angles 25 Degree.46 Degree.66 Degree.88 Degree leg cross section D shape leg sections 3 number legs tube diameter 30-26-22.5 mm material aluminum maximum height 72.05 in maximum height (with center column down) 60.24 in minimum height 3.54 in safety payload 17.64 lbs section center column 1 number weight 7.72 lbsWith Two ZAYKIR Quick Release Plates
