The Blizzard Heavy Duty II N 1.5 aluminum 2-pipe clamp-to-seam snow fence system.  Brackets come with two attached S-5!® N 1.5 standard clamps for standing seam metal panels.  Effective for snow retention in areas with high snow loads.

The S-5!® N 1.5 ("N" stands for Nail strip) is a non-penetrating, standing seam metal roof clamp designed specifically for 1-1/2" nail strip/flange profiles with a seam base dimension up to 0.50" (12.7 mm).  Includes 4 stainless steel setscrews per bracket.

The S-5!® standing-seam clamps are designed to affix directly to the vertical seams of the metal panels without penetrating the seam by tightening the included stainless steel setscrews.
