Add filters to your matte box with this Filter Support from SmallRig. This compact support accepts up to two 100 x 100mm or 100 x 150mm size filters for use with SmallRig Matte Box models 4409, 4411, and 4412, which include an adjustable clamp.

The filters easily install and lock in the support with a single press, and the assembly then aligns with the adjustable clamp. The support ensures there is no vignetting for lenses with a focal length of ≥16mm.
