Scrim Jim is a strong, collapsible diffusion and reflector system. Frames are made of lightweight aircraft aluminum. Modular construction allows you to create three easy-to-handle frame sizes. The unique modular design allows for easy portability as well as quick set-up and take-down. Fabrics are of the highest quality and have hook and loop tape sewn around the perimeter for an even, taut and secure fit to the frame, even during periods of strong winds.
