This is a Matthews 20 x 20 ft, Gridcloth, to fit any Matthews, or other brand or make frame.
Matthews fabrics are tested for even light distribution in a black chamber with an incandescent light source at one end and the fabric positioned 2/3 of the way between the source and the digital light meter. This gridcloth provides slight diffusion and minimal light loss.
