Load Tables

  1. Truss or rafter must be bearing on top plate to achieve the allowable loads under "Without Gap."
  2. Clips are required on both sides of the truss to achieve F1 loads in both directions (stagger parts to avoid screw interferences).
  3. See Fastening Systems and Direct Fastening for more information on Simpson Strong-Tie fasteners.

  1. Allowable loads may not be increased for wind or seismic load.
  2. Clips do not replace stud lateral or stability bracing. Design of bracing is the responsibility of the Designer.
  3. It is the responsibility of the Designer to verify the adequacy of the stud. Allowable loads are based on clips installed an adequate distance away from penetrations, notches, ends of studs and other conditions that may affect the clip performance.
