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

The Blizzard Heavy Duty II NH 1.5 aluminum 2-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.

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