Uplift loads are based on Doug Fir, and have been increased 33% and 60% for earthquake or wind loading with no further increase allowed; reduce where other loads govern. 2. Roof loads are 125% of floor loads unless limited by other criteria. 3. The minimum header depth to achieve the maximum nail configuration is 16". 4. NAILS: 10d 0.148" dia. x 3" long, 10dx1 0.148" dia. x 1 long. See page 16-17 for other nail sizes and information Do not nail within 1/4" of multiple ply seam.

Designed for I-joists, the THAI has extra long straps and can be field-formed to give height adjustability and top flange hanger convenience. Positive angle nailing helps eliminate splitting of the I-joists bottom flange. MATERIAL: THAI-2-14 gauge; all others-18 gauge FINISH: Galvanized INSTALLATION: Factory-order the THAI-2 for hanger width needed. See table for allowable widths. Use all specified fasteners. Verify that the header can take the fasteners specified in the table. Web stiffeners are required for all I-joists used with these hangers. When a total of 20 face nails are used in THAI straps, or 30 face nails are used in THAI-2 straps, the maximum load-carrying capacity is achieved. 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 ". CODES: See page 12 for Code Listing Key Chart. THAI (THAI-2 similar) RC Ripper Clip The Ripper Clip is designed to connect ripped 2x framing to the top of another wood joist. MATERIAL: 20 gauge FINISH: Galvanized INSTALLATION: Use all specified fasteners. Refer to General Notes. Attach RC to ripper, then attach ripper/RC assembly to roof joist. CODES: See page 12 for Code Listing Key Chart. Model No. W Fasteners Allowable Uplift Load F1 F2 Ripper Joist (133) RC1.56 205 240 205 RC1.81 2-10dx1 2-10dx1 RC2.1 1 1 2 170 Code Ref. 1. Allowable loads are for DFL ripper members. 2. Uplift loads have been increased 33% for earthquake or wind loading with no other increase allowed. Reduce by 33% for normal loading. 3. Designer to consider stability/blocking requirements for system, if necessary. 4. Spacing of RC per Designer. 5. NAILS: 10dx1 0.148" dia. x 1 long.
