Standing seam, R-panel, and corrugated roofs are notoriously difficult to protect — luckily, our Accu-Fit Metal Deck Rail system offers the perfect solution! For a standing seam roof, our mounting plates simply clamp on to the vertical seam without any penetration; and, for R-panel and corrugated roofs, we provide a screw-down attachment with gasketed self-sealing hardware. Available in both Traditional and Architectural Series stanchion options.
