Sno Gem Inc. has released its Gem Series Clamp-To-Seam snow-retention systems for standing-seam metal roofs. Available in single- or double-bar retention in 1- and 2-inch bar sizes, the series’ MEC Bracket allows for multiple bar heights and variations to accommodate any snow-retention need, and the Gem Clamp with MEC Bracket is available in a variety of sizes and configurations so it can be attached to most standing-seam profiles. The company’s patent-pending WaveLock Technology with five points of attachment provides strength. Sno Gem’s Silver Bullet set screws include a rounded tip to maximize strength without damaging the paint finish or seam. The systems are available powder coated or with a Kynar finish to match the roof.
