420 1. Allowable loads are for one angle. When angles are installed on each side of the joist, the minimum joist thickness is 3". 2. Some illustrations show connections that could cause cross-grain tension or bending of the wood during loading if not reinforced sufficiently. In this case, mechanical reinforcement should be considered. 3. LTP4 can be installed over 3/8 " wood structural panel sheathing with 0.131" x 1 1/2 " nails and achieve 0.72 of the listed load, or over 1/2 " sheathing and achieve 0.64 of the listed load. 0.131" x 2 1/2 " nails will achieve 100% load. 4. LTP4 satisfies the IRC continuously sheathed portal frame (CS-PF) framing anchor requirements when installed over raised wood floor framing per Figure R602.10.6.4.

5. The LTP5 may be installed over wood structural panel sheathing up to 1/2 " thick using 0.131" x 1 1/2 " nails with no reduction in load. 6. Connectors are required on both sides to achieve F 2 loads in both directions. 7. A34 and A35 installed with 0.131" x 1 1/2 " nails onto 1 1/4 " LSL material will achieve 0.90 of the listed F 1 and F 2 loads. 8. Fasteners: Nail dimensions are listed diameter by length. SD screws are Simpson Strong-Tie ® Strong-Drive ® SD Connector screws. PH612I is a pan-head #6 x 1/2 " screw available from Simpson Strong-Tie. See pp. 21–22 for other nail sizes and information.
