Developed by architectural sheet metal professionals, the Original Polycarbonate™ offers 25 square inches of bonding surface – the larger the base, the greater the holding power. The Original Polycarbonate has the largest base available in the industry! Manufactured from clear UV-stabilized polycarbonate material, or in a color that is injected throughout the product and matched to any standard roof panel. Diagonal installation creates a 7” barrier for more coverage per unit on wider panels. Apply using 3M VHB Tape, tube adhesive, or a mechanical fastening application.
