#80 snow guard for through-fastened metal roofs. Available in aluminum or mild steel, either mill finish or powder coated. Our #80 Omega snow guard fastens to the top of the corrugations to minimize the risk of leakage. The "saddle" design holds back snow and ice while allowing melt-off and rain to flow through. The #80 is available in two styles to fit many different through-fastened metal roofs.
