StiffClip® WC

StiffClip WC

StiffClip® WC connects truss framing web members to chord members. Clip sizes vary with each application. Guide holes are provided in each StiffClip WC for accurate fastener placement. Design loads consider loads on the clip only. Size and number of fasteners used is based on fastener manufacturer’s allowable load data.

Value

  • Stiffened ribs for added strength (use varies with each clip)
  • Guide holes for attachment to framing members (0.172” dia.)
  • No time and expense spent cutting steel shapes
  • Structurally load tested
  • Meets all building code criteria

Notes:

  • Allowable design loads apply to tension or compression on StiffClip WC utilizing the fastener patterns shown.
  • Allowable loads have not been increased for wind, seismic, or other factors.
  • All guide holes may not require fasteners. Number and size of fasteners used is based on fastener manufacturer's allowable load data, and is to be determined by designer.
  • Use of strengthening ribs varies with each clip.

* Load based on structural test.
** Load based on calculations.
