Wooden Camera 231500 - Zip Box 4x4 (90-95mm) Lens Filter

The Wooden Camera Zip Box 4x4 (model 231500) is a minimalist filter holder built for cinematographers and videographers who need to use 4"x4" filters without the bulk or complexity of a traditional matte box. Constructed from stainless steel with a rubber-lined interior clamp, it grips the front of any lens with an outside diameter between 90 and 95mm and holds a single 4x4 filter securely in place. At just 3.66 ounces, it adds almost no weight to your setup, which is particularly beneficial for gimbal and handheld work where every ounce matters.

The clamp-on design means no 15mm rod support is required—you simply open the Zip Box, slide it onto the lens, and tighten. This makes it significantly faster to set up and tear down than rail-mounted matte box systems, and it keeps your rig compact for run-and-gun shooting. The low-profile housing is engineered to minimize vignetting, though as with any clamp-on filter holder, extremely wide focal lengths should be tested before a shoot. For productions that need to stack polarizers with ND filters or require a French flag, a full matte box is still the better tool. The Zip Box excels as a single-filter solution that prioritizes speed, portability, and simplicity.
