Quick Tie Products makes a post-tensioned cable system, which serves as a hold-down to resist shear and uplift in framed walls. A similar cable hold-down for block walls was also introduced at JLC Live. Each Quick Tie consists of a galvanized wire-rope cable with a threaded stud swedged to each end and a plate washer and nut on the upper end. Preordered custom-length cables are installed to run from a building’s uppermost top plate down to the foundation, where the cable end is epoxied into a hole in the concrete; after the epoxy has cured, the cable is tightened by wrenching down on the nut. Price varies by length. quicktiesystems.com
