The Manfrotto MT055XPRO3 Aluminum Tripod is a three-section support that replaces the 055XPROB tripod. It has a load capacity of 44 lb and extends from 3.5" to 67". Its legs are secured by the Quick Power Locks. These updated flip locks increase the tripod's rigidity by 50%, and its load capacity by 4.4 lb over its predecessor.
