MMB 2 Clamp-on Reduction Ring 87mm.

The MMB-2 Reduction/Clamp-On Ring 87mm from ARRI enables you to clamp an MMB-2 lightweight matte box to your 87mm front-diameter lens. This composite ring’s split design gently compresses to hold the matte box securely on the lens, eliminating the weight of a rod-mount system for the matte box.
