0.282kg / 0.62lbs. Direct Load - 160kg / 350lb. Drag Load - 37kg / 81lb. Portrait Load - 37kg / 81lb. 26g / 1oz - Peak Design Capture &Arca Swiss Compatible.Loads capabilities are variable, as there are different ways to apply the load. Direct Load: With the head level and the clamp level, a direct downward load can be applied up to the capacity. Drag: Drag is the load it requires to make the ball move within the head. This is tested by angling the ball and adding pressure until the ball moves. Dont do this when attached to a tripod - your head is a lot more powerful than any tripod can withstand. Portrait: When the clamp is locked sideways in the portrait position, this is the load that the clamp can hold without rotating or moving.
