Vinten 3750-3 Mitchell Base with Wingnut

The 3750-3 takes a pan and tilt head with the standard Vinten four-hole base and mounts it on a Mitchell base. It is the adaptor that keeps a four-bolt head working on a Mitchell-equipped crane, riser or hired support.

It supplies as a Mitchell adaptor with wingnut and key, so the head locks down by hand. Load capacity is 100 kg (220 lb) and it weighs 1 kg. For the opposite conversion, the 3055-3B takes a Mitchell head onto a four-bolt flat base.
