Cello Scrim, is made exclusively for us, of aluminum wire screening with a plastic coating, making it water proof and easily holds its shape. It is most commonly used to protect lighting fixtures and electrical boxes from rain and snow. Cello Scrim is also used in the manufacture of Cucolorises (Cello Cookies). Caution must be taken when placing Cello Scrim too close to a lighting fixture, as the plastic will burn and melt at temperatures over 400o F!Width of rolls vary between 47” and 48” due to some shrinkage in manufacturing process.
