The Blizzard Heavy Duty III U aluminum 3-pipe clamp-to-seam snow fence system.  Brackets come with two attached S-5!® U standard clamps for standing seam metal panels.  Effective for snow retention in areas with high snow loads.

The S-5!® U clamp has multiple hole orientations for use on both vertically/double-fold seams (up to 0.4") and rotated 90 degrees for horizontal/single-fold seam profiles with horizontal projection equal to or greater than 0.65”.​​​​

Blizzard Heavy Duty III aluminum 3-pipe clamp-to-seam snow fence system is our tallest and one of our strongest clamp-to-seam systems for standing seam metal panel roofs.  Use of the Blizzard Heavy Duty III system may reduce the number of rows needed for some roof sections.
