Wooden Camera UMB-1 Universal Mattebox (Clamp On)

The UMB-1 Clamp On ships with two rotating 4x5.65 filter stages (a third stage optional), individual tray catchers, a folding French flag, a 143mm native opening, and NATO-standard accessory rails on left, right, and top. A complete set of clamp-on reduction rings covers common lens barrel diameters out of the box.

Like the rest of the UMB-1 line, it's designed to be user-upgradable in the field - from Clamp On to Swing Away to an ultralight stabilizer configuration - rather than locking a production into one matte box for every camera setup.
