Making its debut in 2014, Sno Gem® is proud to announce the launch of the 2” Bar Sno Blockade™ system to our line of innovative snow retention systems. The Sno Blockade™ system is available in standard mill finish aluminum or painted in either a powder coating or Kynar finish. It is easy to install with few required components, regardless of whether installed on a new or existing standing seam metal roof system. The Sno Blockade™ system’s unparalleled strength is derived from the unique design of the patent-pending WaveLock™ Technology with 5 points of attachment and is designed to maximize strength, but not to pierce or penetrate the roof panel.
