Dual-diameter helical anchor for harder backup material
The PROSOCO Stitch-Tie Asymmetric, formerly called CTP Stitch-Tie Asymmetric, features one end with a smaller diameter that makes it ideal for embedding into harder backup materials. The 8-mm or 10-mm helical outer diameter on the other end is designed to engage with softer masonry veneer materials. The result provides an optimum tension capacity for the connection.
FEATURES
- Simple installation with minimal disturbance; Self-taps directly into a small pilot hole drilled into the substrate.
- Helical design ensures continuous grip.
- Color-coded for quick and easy installation.
- Installs with rotary hammer and appropriate setting tools.
OVERVIEW
The CTP Stitch Tie Asymmetric is used when connecting a soft external substrate to harder internal walls. The CTP 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. CTP recommends a mock-up installation at the site to establish the need for CTP Stitch Tie Asymmetric. At that time, development of an optimum pilot hole size can be established.
