UpRight scaffolds feature the original "Rib-Grip" system. High strength tubing is hydraulically cold-formed to lock mechanically into pre-cast grooves outside and inside the heat-treated cast Aluminum fittings. This method of producing Aluminum frames and components gives tensile joint strengths up to three times greater, and durability many times higher than that of traditional welded types. UpRight scaffolds offer a modular, cost effective and safe means of access to job sites.
