Blizzard II (Assembled S-5!® DualGard) with NH1.5 Mini Clamps

Fence-Style Snow Guard Bracket

Aluminum 2-pipe snow fence bracket with two attached S-5!® NH 1.5 Mini clamps for standing seam metal panel roofs.  Effective for snow retention in areas with low to moderate snow loads.

The S-5-NH 1.5 ("NH" stands for Nail strip Hinge) Mini clamp is designed specifically for 1-1/2" tall nail strip standing seam metal roof profiles with a wider horizontal dimension (>0.475" and up to 0.80").

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 directly to the vertical seams of the metal panels without penetrating the seam by tightening the included stainless steel setscrews.
