The Certifix DSH-3-Z Distance Set is a high-performance, one-person fastening solution designed to simplify the installation of light panels on steel and aluminum substructures. Perfect for outdoor projects such as carports, pergolas, and canopies, this set arrives fully pre-assembled with the screw, seal, and sleeve integrated into a single unit. This "out-of-the-box" readiness eliminates the need for the traditionally cumbersome two-person installation process, allowing for a faster, more cost-effective workflow on the job site. Engineered for durability and precision, the set features a 5.5 x 50 bi-metal construction—combining A2 stainless steel and steel with a premium RUSPERT® coating for superior corrosion resistance. One of its standout features is the large umbrella sealing system (E16+SD19), which provides a significantly improved seal by adapting perfectly to the contours of corrugated profiles during compression. With a hexagon head for secure AF 8 driving and a partial thread design, the Certifix DSH-3-Z ensures a watertight, professional finish that protects the structural integrity of your roofing projects.
