Profile: Polar Blox, Inc. is in the business of developing snow guards for all types of roofing. These guards are made of tough, high-izod polycarbonate plastic. It features 4 interior stabilizers to withstand up to 2,500 lbs. These are available in various custom colors. These are UV protected and will not fade or break down from sun or harsh weather. Our Standing Seam Guard is effective where ice and heavy snow are problems. The standard bottom bar keeps ice and snow from sliding while the optional top bar holds back deeper snow. These guards are made to fit straight seams or T & L seams up to 2 inches tall and are available to fit different pan widths.
