The Blizzard Heavy Duty II H aluminum 2-pipe clamp-to-seam bracket with two attached S-5!® H standard size clamps for clamp-to-seam fence-style snow retention systems in areas with high snow loads.  The S-5!® standing-seam clamps are designed to affix directly to the vertical seams of metal panels without penetrating the seam by tightening the included setscrews.

The S-5!® H clamp is designed to accommodate horizontal seams (single-folded) that are not fully closed that include a vertical leg.  The setscrews are side-install rather than top-down on metal standing seam roofs.  Includes 2 aluminum inserts and 4 stainless steel setscrews per bracket.

Blizzard Heavy Duty II bracket is part of a complete system designed for applications with high snow loads.  This is one of our strongest clamp-to-seam systems for standing seam metal panel roofs.  Use of the Blizzard Heavy Duty II bracket may reduce the number of rows needed for some roof sections.
