SKU CH-AD9M-VY8BX

A 100 mm clamp-on back attaches the Zip Box Pro 4x5.65" matte box to 100 mm lens fronts, weighing 0.10 kg for lightweight, secure mounting

  • Adds minimal bulk at .22 lbs for easy handling
  • Fits 100mm lens fronts for versatile compatibility
  • Securely attaches to Zip Box Pro 4x5.65" matte box
  • Prevents light leaks with a wobble-free connection
  • Simple four-screw installation for quick setup

Purpose and User

This clamp-on back adapts the Zip Box Pro 4x5.65" matte box to lenses with a 100mm front diameter. It is built for cinematographers and camera operators who need to mount the matte box directly on the lens rather than on rails. The accessory suits both studio and location work where quick lens changes are common.

Build and Daily Use

The part weighs 0.22 lbs (.10 kg) and adds minimal bulk to the front of the lens. Four included screws secure it to the matte box for a rigid, wobble-free joint that prevents light leaks. Its lightweight construction keeps the overall rig balanced during handheld or gimbal operation.

Deciding Specification

The clamp accepts only 100mm lens fronts, so it will not fit smaller or larger diameters without a step-up or step-down ring. Buyers whose lenses use a different thread size must add an adapter ring or choose a different clamp-on back.
