A wind clamp, otherwise known as an “external seam clamp,” is a small aluminum clamp placed over the seam at given intervals to prevent male-to-female seam separation and/or seam separation from its mounting clip. The wind clamp significantly increases the wind-resistance capacity of the panel system. It can also help prevent clip disengagement when used at clip locations. Actually, any of our seam clamps will improve wind resistance of the roof and can be used for that purpose. Our WindClamps, however, are specially designed solely for this purpose on select concealed-fastened seam profiles, so they are even more effective and more economical in quantity.
