Blizzard Heavy Duty II with S-5!® H90 Clamps

Fence-Style Snow Guard Bracket

The Blizzard Heavy Duty II H90 aluminum 2-pipe clamp-to-seam bracket with two attached S-5!® H90 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.

Use the S-5!® H90 clamp on metal standing seam panel roofs with fully seamed horizontal, single-folded seams greater than 0.65” (16.5 mm) wide.  The setscrews are top-down oriented.  Includes 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.
