StiffClip® RT

TSN_StiffClip_RT

StiffClip® RT series secures and ties down roof framing members. StiffClip’s unique shape incorporates stiffened legs to increase compressive strength and resist horizontal, lateral, and uplift loads. The allowable design load table shown is based on the use of StiffClip as it is attached to various steel stud material thicknesses and yield strengths. Design loads consider loads on the clip and the use of #12 screw fasteners relative to the framing material.

Value

  • Stiffened ribs for added strength
  • Guide holes for attachment to framing members (0.188” dia.)
  • Engineered for steel members
  • Structurally load tested
  • Meets all building code criteria

Nomenclature

StiffClip RT650 is 6½" long, and may be used when wall studs do not align with roof framing member. The RT1300 is 13" long, and is used when wall studs align with roof framing member. Clips are designated by length, followed by thickness and number of screws used in each leg (determined by load requirements - refer to load tables).

Example: Stud aligns with roof framing member (see application image)
Designate: StiffClip® 1300

* StiffClip RT650 are packaged in pairs. (shown right)

Load Directions:
F1 = Lateral F2 = Horizontal F3 = Uplift

  • StiffClip RT resists horizontal, lateral, and uplift loads.
  • Allowable loads have not been increased for wind, seismic, or other factors.
  • Number of screws designated represents the amount required in each leg of the clip.
  • Loads listed reflect force in a single direction. When multiple loads act on the connection, it is the responsibility of the designer to check the interaction of forces.
  • Torsional effects are considered on screw groups for F1, 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.
