Egg Crate Fabric Grids available in 20, 40 and 60 degree concentrated, hard-edged light when combined with the Scrim Jim system for the 42" x 42" and 72" x 72" sized frames. Hook and loop tape quick-release tabs provide easy set-up and tear down. A diffusion fabric of your choice is easily applied to the outside perimeter of the frame using hook and loop tape. Like other Westcott equipment, the egg crate grids are extremely portable. Made of lightweight fabric, the fabric grids are fan-folded into small strips, tied with a hook and loop tape strap and stored in a heavy duty-carrying bag.
