A seasonal item, but almost indispensable when snow piles up. These blades are made from # 22 SBR belt cover stock for extra abrasion resistance. Popular sizes are 1″ and 1-1/2″ thick x 6″ to 12″ wide, and in lengths of 50′ and 100′ rolls . These blades are bolted onto the business edge of the road patrol and used to remove snow from highways, parking lots, airport runways and other public areas.
