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

The Blizzard Heavy Duty III U aluminum 3-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 90* for use on many horizontal/single-fold profiles with horizontal projection of 0.65" to 7/8".  Includes 4 stainless steel setscrews per bracket.

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