OUR PART # WC-202100
UMB-1 Universal Mattebox (Pro) is natively 15mm LW rod based and comes standard with two rotating 4x5.65 filter stages (with an optional third stage available), individual tray catchers, folding French flag, 143mm native diameter opening, NATO standard accessory rails on left, right, and top for attaching accessories, ARRI style rubber bellows with 114mm standard opening, a complete set of bellows reduction rings, a universal cloth donut for non-standard lens diameters, a height adjustable swing away bracket, left and right side flags, bottom flag, and a full set of clamp on adapter rings. The UMB-1 is designed to quickly transition from swing away, to clamp on, to ultralight when using a stabilizer.
Reduction rings snap into the bellows quickly making lens transitions fast and easy. Another great feature of these reduction rings is that they are compatible with all 3rd party 114mm threaded bellows since they have specially designed tabs.
Adaptable to 15mm Studio and 19mm via the Universal Mattebox (15mm Studio Adapter) and Universal Mattebox (19mm Adapter).
