Thank you for viewing this item. This is a large tripod made by SLIK. The total height is 1550mm, and the maximum height when the center pole is extended is 1925mm, with a leg diameter of 30.2mm. The material is an alloy of aluminum, magnesium, and titanium, making it lighter and more rigid than typical tripods in the same class. While there is some wear and tear, there is no looseness, and there are no issues with the required functions. Please feel free to comment if you have any questions or requests for additional photos. #SLIK #Slik #Tripod
