For H2.5A only - Products can be on the same side of the wall provided they are configured as shown. Nailing into both sides of a single ply 2x truss may cause the wood to split. H9 attaching truss to top plates 14 H7Z Installation H8 attaching stud to sill (4-8d into plate, 5-8d into stud) H8 attaching I-joist to double top plates H9, H10 and H10R optional positive angle nailing connects shear blocking to rafter. Use 8d common nails. Slot allows maximum field-bending up to a pitch of 6/12, use 75% of the table uplift load; bend one time only. 17 Considerations for Hurricane Tie Selection 1. What is the uplift load? 2. What is the parallel-to-plate load? 3. What is the perpendicular-to-plate load? 4. What is the species of wood used for the rafter and the top plates? (Select the load table based on the lowest performing species of wood.) 5. Will the hurricane tie be nailed into both top plates or the upper top plate only? 6. What load or loads will the hurricane tie be taking? 7. Select hurricane tie based on performance, application, installed cost and ease of installation. Allowable simultaneous loads in more than one direction on a single connector must be evaluated as follows: Design Uplift/Allowable Uplift Design Lateral Parallel to Plate Allowable Lateral Parallel to Plate Design Lateral Perpendicular to Plate Allowable Lateral Perpendicular to Plate 1.0. 2 1 15 H8 attaching rafter to double top plates H14 Installation to double 2x header 22 VB Knee Braces The VB provides lateral resistance force at the bottom of beams when installed approximately 45 or more to the vertical plane. MATERIAL: 12 gauge. FINISH: Galvanized INSTALLATION: Use specified fasteners. See General Notes. 16-N54A fasteners are included with the brace. CODES: See page 12 for Code Listing Key Chart.
