The Sno Shield Rib Guard standing seam snow guard 1 5/8" is made to attach to standing seam metal roofs shorter than 1 5/8" without penetrating the rooftop panel. This snow guard is attached to the standing seam rib using two stainless steel set screws and multiple structural cleats. This "clamp-on" style snow guard helps avoid potential leaks and warranty infractions. The Rib Guard is made in two widths to accommodate different standing seam profiles. Customize the Rib Guard with Sno Shield's Color Armor for a perfect match to any metal roof.
