The Chrosziel 510-01 is a precision-machined multi-format filter tray designed for professional matte boxes that feature 150mm wide filter compartments, including the Chrosziel 805 series. This versatile accessory allows cinematographers to use both square 5x5" filters and rectangular 4x5.65" filters within the same tray, eliminating the need to carry different trays for different filter formats.

The tray construction prioritizes security and ease of use. A spring-loaded catch mechanism holds the filter firmly in place during camera moves, preventing unwanted shifting or rattling that could affect image quality. Chrosziel specifically recommends using filters in a horizontal orientation when operating with this tray, which aligns with standard professional practices for graduated and polarizing filters.

One of the primary advantages of the 510-01 design is the ability to purchase multiple trays and pre-load them with different filters before a shoot. This workflow dramatically reduces downtime on set, as camera assistants can simply swap entire trays rather than carefully inserting individual filters between shots. The tray serves as an ideal replacement for damaged, worn, or missing units, and is commonly included as standard equipment with Chrosziel matte boxes such as the 456 Academy Double and 456-20 Academy MatteBox configurations.
