StiffClip® JC

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 (0.172" in diameter)
  • Structurally load tested

Nomenclature

StiffClip JC is designated by listing the joist depth in inches, followed by the required clip thickness in mils that will accommodate anticipated loads. (see technical sheet for load tables)

Example: 6" joist, 3,000 lbs. load
Designate: StiffClip® JC600-68

Notes:

  • StiffClip JC resists vertical loads.
  • The attachment to the beam or structure must be designed to be greater than or equivalent to the joist attachment.
  • Design loads consider clip capacity and screw connection to the joist 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 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. ½ in the joist connection and ½ in the structure connection.
