Wooden Camera UMB-1 Universal Mattebox (Pro)

The UMB-1 Pro is natively 15mm LW rod based, with two rotating 4x5.65 filter stages (a third optional), a folding French flag, a 143mm native opening, and NATO-standard accessory rails on left, right, and top. ARRI-style rubber bellows with a 114mm standard opening pair with a complete set of snap-in reduction rings that share tabs compatible with third-party 114mm threaded bellows, making lens changes fast.

A height-adjustable swing-away bracket, left and right side flags, a bottom flag, and a full clamp-on adapter set are all included, and the whole system adapts to 15mm Studio or 19mm rods via the separate Universal Mattebox adapter accessories. It ships in custom foam sized for a Pelican 1550 hard case (not included).
