Snow Boss #640 are solid cast aluminum snow guards, "traditional shaped" for the mid-panel application on all standing, batten, and flat seam (non-copper) metal roofs. These aluminum guards are available mill finished or custom color matched using Dupont® Imron enamels. Typical installation is by means of high strength adhesives (SB-190) that develop superior peel and shear bonding strength on modern metal roofs coated with plastic resin paints such as Kynar®.
