StiffClip^® CL

Nomenclature

To specify Stiff Clip CL on drawings, multiply stud depth by 100, followed by the appropriate material thickness, based on strength required (see technical sheet for load tables). The Stiff Clip CL118(H) utilizes a plate in the 1½” leg (shown in application image).

Example: 6” stud, uplift load of 650lbs.
Designate: StiffClip^® CL600-68.

Notes:

• StiffClip CL resists vertical, horizontal, and torsional loads.
• Allowable load tables incorporate eccentric loading of fasteners. Values with welded connection may increase.
• Fasten within ¾” from the angle heel (centerline of the 1½” leg), using pre-drilled holes.
• Center hole is 0.563” in diameter for ½" anchor. Middle guide holes are 0.313” in diameter. Outer guide holes are 0.172” in diameter.
• Guide holes are in place for fastener installation efficiency. All guide holes may not require fasteners. Fastener amount determined by the designer. Screw fasteners should be symmetrically placed in guide holes. Refer to screw pattern diagrams for placement.
• Loads listed reflect force in a single direction. When multiple loads react on the connection, it is the responsibility of the designer to check the interaction of forces.
• Allowable loads have not been increased for wind, seismic, or other factors.
• 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.
• M1 loads are reported as Max. Load divided by a Factor of Safety. M1 loads maybe limited by the Serviceability Load calculated as Clip Stiffness times the Serviceability Limit in radians.
• Stiffness is the Allowable Clip Moment divided by the clip rotation measured at Half the Max Allowable Clip Moment.

Load Direction

The following equation for tension force in the anchor is derived using the assumed bearing stress distribution shown in the image. This assumed stress distribution provides a conservative anchor force approximation.
