The Tiffen Multi Rota Tray (MRT) is a geared rotating tray that allows the use and rotation of a 138mm Circular Polarizer and Variable ND in a 4×5.650 tray and is ideal for matte boxes without a rotating filter stage or for those instances where a secondary rotating filter stage is required in a non-rotating stage.
The Tiffen Multi Rota Tray is designed to fit into a variety of Matte Boxes which conform to ARRI R2 design standards.
