Product Application The StiffClip® LS series is to be utilized when connecting framing members in various applications, the most common being connecting spandrel wall studs to structure. StiffClip LS resists axial tension and compression loads. Allowable design loads may be calculated based on the Section Properties shown below. Long lengths greater than 20” incorporate stiffened legs to increase compressive strength. Design loads consider loads on the clip and #12 screw fasteners to stud web.

Material Composition Steel: ASTM A653/A653M, Grade 50 (340), 50ksi (340MPa) minimum yield strength, 65ksi (450MPa) minimum tensile strength, G-90 (Z275) hot-dipped galvanized coating. Material thickness: 68mil (14ga, .0713” design thickness). The attachment of StiffClip to the structure may be made with either a PAF or weld and is dependent upon base material properties and the design configuration. Note: For PAF’s, fasten within ¾” from the angle heel centerline of the 1½” leg.

• Various lengths allow flexibility
• Eliminates shims and scabs to accommodate stud tolerance from structure in spandrel walls
• Manufactured from mill certified steel

StiffClip LS is available in various lengths (8”, 10”, 12”, 15”, & 20”). To calculate length for spandrel wall connectors, add stud depth, 3” for attachment to steel (5.5” for attachment to concrete), and the distance of construction tolerance. For other applications, simply designate length (in.) multiplied by 100.

Example: 6” stud, 4” attachment to structure, 2” tolerance. (6+4+2=12)

Designate: StiffClip LS1200.
