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

Fence-Style Snow Guard Bracket

The Blizzard Heavy Duty II U aluminum 2-pipe clamp-to-seam bracket with two attached S-5!® U 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!® U clamp on metal standing seam roofs with mechanically fastened vertical/double-fold seams up to 0.4" or rotate clamp 90* for use on most horizontal/single-fold seam profiles with horizontal projection up to 0.65".  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.
