The Manfrotto 338 leveling head is a solid, all-metal leveling head designed to slot in between the head and legs of your existing tripod. The three independent thumbscrews provide fine-grained control of leveling for critical shooting. 3/8” threads on top and bottom for leg and head connection. The head mounting platform is wide and should fit nearly any head; the maximum clearance for the tripod leg top plate is the Manfrotto-standard 6cm, so this won’t fit broad-top Gitzo tripods. In good cosmetic condition, with minor surface and finish wear from normal use. Function is excellent.
