Berger 2.83 in. H X 4.9 in. W X 2.75 in. L Galvanized Malleable Iron Snow Guard

Snow guards are intended to prevent snow movement and breakdown of the snow mass into smaller sections, reducing the potential for snow and ice damage to gutters, foundation, plantings, parked vehicles, adjacent roofs and equipment and injury to pedestrians. The #20 Snow Guard is designed to fit on the crown (top) of the 1 1/4 in and 2 1/2 in. rounded corrugated metal roofing. Use neoprene washer screws to fasten. Do no use adhesives to secure, only to keep water out.
