How the Stitch Plate™ Works
The Stitch Plate™ bridges a membrane incision as a single structure. The joint line at the center aligns precisely with the cut. One or more fasteners on each side penetrate the membrane, insulation, and deck, locking both sections as a unified unit. Downward-facing barbs grip the membrane surface to resist rotation and wind uplift. Concentric ribbing provides rigidity with controlled flexibility — the feature the USPTO cited as novel over all prior art.
Available as a standalone plate or as a complete repair kit with fasteners.
