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

The S-5!® Q Clamp ("Q" represents the shape of the clamp) allows for the attachment of snow guards and other heavy-duty applications to metal roof panels featuring large "bulb" seam configurations up to 1.14" (29 mm).

The clamp features a two-piece design that makes it easy to install anywhere along the seam.

The S-5!® Q Clamp also fits smaller, round "bulb-shaped" profiles with diameters of 0.75" (19 mm) or less if the seam is not properly closed. 

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.
