Blizzard Heavy Duty III with S-5!® NH1.5 Clamps

The Blizzard Heavy Duty III NH 1.5 aluminum 3-pipe clamp-to-seam snow fence system.  Brackets come with two attached S-5!® NH 1.5 standard clamps for standing seam metal panels.  Effective for snow retention in areas with high snow loads.

Use the S-5!® NH 1.5 ("NH" stands for Nail strip Hinge) is a non-penetrating, standing seam metal roof clamp designed specifically for 1-1/2" nail strip profiles with a wider horizontal dimension (>0.475" and up to 0.80").  Includes 2 aluminum inserts and 4 stainless steel setscrews per bracket.

The innovative insert is a "hinge" design and features a toe to engage the female portion of the panel.  The aluminum insert forms to the shape of the seam, preventing damage at the point of attachment, while offering optimal holding strength.  The aluminum hinge insert is staked at one end to facilitate installation and is reversible to allow for proper fit on both wide and medium-width profiles. Blizzard Heavy Duty III aluminum 3-pipe clamp-to-seam snow fence system is our tallest and one of our strongest clamp-to-seam systems for standing seam metal panel roofs.  Use of the Blizzard Heavy Duty III system may reduce the number of rows needed for some roof sections.
