Wooden Camera UMB-1 143-95mm Mattebox Clamp On Reduction Ring

SKU CH-AY2P-1ESV6

Adapts 143mm matte boxes to 95mm lenses with a secure, tool-free clamp-on design

  • Adapts 143mm matte boxes to 95mm lenses for broader equipment options
  • High-grade construction withstands rigorous use for long-lasting reliability
  • Lightweight design minimises added weight for comfortable handling during extended shoots
  • Tool-free clamp attachment streamlines workflow with swift lens changes
  • Converts Universal Mattebox Base or Swing Away versions to clamp-on operation

Compatibility & Use

The Wooden Camera UMB-1 reduction ring adapts a 143mm Universal Mattebox to 95mm front-diameter lenses. It lets cinematographers use the same matte box across different lens sizes without swapping the entire unit. The clamp-on design attaches directly to the lens barrel for a secure, wobble-free connection during professional film and video production. No tools are required for installation or removal.

Capacity & Limits

The ring bridges the 143mm matte box opening down to a 95mm lens thread, covering that specific size step only. It adds minimal weight to the front of the lens, preserving balance and handling during extended shoots. The adapter does not support lenses with front diameters larger than 143mm or smaller than 95mm, nor does it convert other matte box brands or sizes.

Critical Specification

This part only works with the Base or Swing Away versions of the Wooden Camera Universal Mattebox. It will not fit matte boxes from other manufacturers or different Wooden Camera models. Verify your matte box version and lens front diameter before purchasing.

Questions about this item

Will the 143mm matte box clamp securely onto my existing 95mm lens threads?

The reduction ring converts a 143mm Universal Mattebox to a clamp-on fit for 95mm lenses, providing a secure, wobble-free connection without tools.

How can I verify the ring is seated correctly on the matte box after attaching it?

The clamp mechanism engages firmly around the 143mm matte box front; a stable, gap-free join with no rotational play confirms proper seating.

Does the package include the Universal Mattebox or only the reduction ring?

Only the UMB-1 clamp-on reduction ring is supplied; the Base or Swing Away Universal Mattebox must be purchased separately.
