The Matthews Open End Scrim Frame (18 x 24") is made of spring steel with a 3/8" pin and support which can be used to hang the Scrim from the C Stand handle when not in use. The two upright arms of the frame are slotted at the two open ends to retain the piano wire woven through the fabric to make up the fourth side of the frame without causing a shadow.
