Kupo Mitchell Wrench (WS-229)

Overview

The Kupo WS-229 Mitchell Wrench is a professional heavy-duty rigging tool designed for tightening and loosening Mitchell-style castle nuts used in camera support and grip systems in film production, television, and studio environments.

Constructed from stainless steel, the wrench is built for durability and long-term use in demanding production settings. It features a series of concentric cut-outs that align with Mitchell castle nuts in multiple positions, allowing the user to apply controlled torque regardless of the nut’s orientation. This makes it especially useful in tight rigging setups where access is limited.

The central handle incorporates an M12 interface, which aligns with common professional rigging requirements and adds additional utility for on-set applications. Its solid, weight-balanced design ensures reliable grip and leverage when working with heavy-duty Mitchell base systems.
