The StiffClip® CL series’ unique design allows for the connection of steel studs to the building’s structure by incorporating stiffened legs of a 90o angle to increase bending strength. StiffClip CL resists vertical, horizontal, and torsional loads. The allowable design load table is based on the use of StiffClip as it is attached to various steel stud wall material thicknesses and yield strengths. Allowable loads consider loads on the clip and screw fasteners to the stud web. Pre-drilled holes for attachments to both deck and stud provide installers with increased efficiency. The designed attachment of StiffClip to the primary structure is dependent upon the base material’s properties (e.g. steel or concrete) and the design configuration.
Allowable load tables incorporate eccentric loading of fasteners. Values with the welded connection may increase.
When determining the allowable load of fasteners securing StiffClip to the base material and clip to stud, consider the following:
Fasten within ¾” from the angle heel (center line of the 1½” leg), using pre-drilled holes if desired
Center guide hole is .5” in diameter
Middle guide holes are .313” in diameter
Outer guide holes are .172” in diameter
Guide holes are in place for fastener installation efficiency. Number of fasteners determined by designer
Attachment to stud is made with #12 screws, symmetrically placed
