The Wooden Camera UMB-1 Universal Mattebox (Pro) is a native 15mm LWS rod mount swing-away mattebox, with two rotating 4" x 5.65" filter stages (optional third stage available), individual tray catchers, a folding French flag, 143mm diameter (R2) bellows adapter, NATO standard accessory rails on left, right, and top for attaching accessories, ARRI-style (R2) rubber bellows with 114mm standard threaded insert ring, a complete set of bellows reduction rings, universal cloth donut for non-standard lens diameters, 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 thanks to specially designed tabs.
