The Blizzard Heavy Duty II Z aluminum 2-pipe clamp-to-seam snow fence system.  Brackets come with two attached S-5!® Z standard clamps for standing seam metal panels.  Effective for snow retention in areas with high snow loads.

Use the S-5!® Z clamp on metal standing seam roofs with round "bulb" seam configuration and seam diameter of 7/8" (22 mm) or less.

The S-5!® standing-seam clamps are designed to affix directly to the vertical seams of the metal panels without penetrating the seam by tightening the included stainless steel setscrews.
