StiffClip® JC

StiffClip® JC series connects floor joists to beams and other structural components while resisting vertical loads. Pre-drilled guide holes and a support flange streamline installation. The allowable load tables shown below are based on use of StiffClip JC attached to various joist thicknesses and yield strengths with #12 Screws. The attachment to the beam or structure must be designed to be greater than or equivalent to the joist attachment.

Value

  • Joist flange rests on angle leg for fast joist installation
  • Guide holes for attachment to beam and screw placement to member (.172" in diameter)
  • Structurally load tested

  • Design loads based on clip capacity only.
  • Allowable loads have not been increased for wind, seismic, or other factors.
  • All guide holes may not require fasteners.
  • Fastener size and amount determined by designer.
  • Torsional effects are considered on screw group for F2 & F3 allowable loads. It is assumed that half of the torsional moment is taken by the connection to the structure and half is taken by the connection to the stud, i.e. 1/2 in the joist connection and 1/2 in the structure connection.
