Sno Gem Inc., a manufacturer of snow-retention products for self-storage and other industries, has released its Gem Series Clamp-To-Seam snow-retention systems designed to attach to most standing-seam metal roofs. The series is available in single- or double-bar retention, with bar sizes of 1 or 2 inches. Both configurations offer clamp-to-seam attachments using an MEC Bracket, which allows for multiple bar heights and variations, depending on need, according to a press release.

The company’s patent-pending WaveLock technology provides five points of attachment for strength, and its Silver Bullet set screws have a rounded, bullet tip designed to maximize strength without damaging the paint finish or seam, company officials said. The systems are available powder-coated or with a Kynar finish.

Based in McHenry, Ill., Snow Gem’s principals have leveraged more than 100 years of combined experience in architectural sheet metal and roofing to develop the company’s line of snow guards. The company also offers solar-panel and roof-accessory attachments.
