The Simson THAI Adjustable Hanger is designed for I-joists and features extra-long straps that can be field-formed for height adjustment and top-flange hanger convenience. Positive-angle nailing prevents the bottom flange of the I-joist from separating. There is no longer room for increasing the uplift loads for earthquake or wind loading. Where other loads are govern, reduce.

Use all specified fasteners. Verify that the header can take the fasteners specified in the table.

• Reduce load given by allowable nail shear capacity for each nail less than maximum.
• A minimum nailing configuration is shown for top nailing installations. The strap must be field-formed over the top of the header by a minimum of 2 1/2".
