The S-5-S ("S" stands for snap-lock) is a non-penetrating, standing seam metal roof (SSMR) clamp. The S is designed for most popular vertical snap-together profiles - typically with vertical dimensions of 1.5" (38 mm) and 1.75" (44 mm). The S is also the perfect solution for traditional, single-fold (angle-seam) horizontal profiles of 1" (25 mm) and 1.5" (38 mm) seam height dimensions and all similar seam types.
