The Stitch-Tie Asymmetric is used when connecting a soft external substrate to harder internal walls. The Stitch-Tie Asymmetric features one end with a smaller diameter (2”-3”) to embed into harder back-up material. The 8-mm or 10-mm helical outer diameter on the other end is designed to engage with softer masonry veneer material. The result provides an optimum tension capacity for the connection. This is important because concrete back-up density and hardness can restrict entry of 8-mm or 10-mm diameter helical ties. A larger pilot hole would usually be required. By concurrently enlarging the veneer pilot hole, a capacity reduction in the veneer portion of the anchorage can occur. PROSOCO recommends a mock-up installation at the site to establish the need for Stitch-Tie Asymmetric. At that time, development of an optimum pilot hole size can be established.
