The Alphatron Broadcast Electronics 114 to 85mm Step Down Adapter Ring allows you to use available clip-on matte boxes, such as an Alphatron 4 x 4, with available lenses that feature an outer lens barrel diameter of 85mm. The adapter ring is made from black anodized aluminum and features a split ring design. The split ring design allows you to use a minimum amount of force attaching and removing the ring, compared to non-split ring adapters, and this lessens the wear on the lens when attaching and removing the adapter/matte box.

When the adapter is mounted into an available clip-on matte box with a 114mm rear opening, the spring pressure from the split ring should hold it in place. Then mount the matte box on the lens, and tighten the clamp to secure the matte box to the lens.
You can stack this split ring adapter with an available 138 to 114mm adapter, which allows you to use a clip-on matte box with a 138mm rear opening with your lens with an 85mm outer lens barrel diameter. Please note that stacking more than one split ring adapter for clip-on matte boxes should be considered a last resort, and it is advisable to use one ring of the correct size, or a different matte box.
