Frequently Asked Questions
- What joist sizes is the THAI422 compatible with?
- The THAI422 is designed for members with a joist width of 3-1/2 in. and a joist depth ranging from 9-1/4 in. to 14 in. Compatible member types include 3-1/2 in. I-joists, 4x10, 4x12, and 4x truss.
- What fasteners are required to install the THAI422?
- Installation requires (6-20) 0.148 in. x 3 in. nails in the header and (2) 0.148 in. x 1-1/2 in. nails in the joist. Always use all specified fasteners and verify that the header can accommodate the specified nailing pattern.
- How does the THAI422 achieve height adjustability in the field?
- The THAI422 features extra-long straps that can be field-formed over the top of the header, providing height adjustability and top-flange hanger convenience without requiring factory pre-configuration for every joist depth within the 9-1/4 in. to 14 in. range.
- Why is positive-angle nailing (PAN) important for I-joist hangers?
- Positive-angle nailing (PAN) drives nails at an angle that directs force away from the I-joist's bottom flange, helping to eliminate splitting of that flange during installation - a critical consideration for maintaining the structural integrity of engineered wood I-joists.
