StiffClip® LS

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. Long lengths greater than 20” incorporate a stiffening lip to increase compressive strength.

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

Nomenclature

StiffClip LS is available in various lengths. 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.

Material Composition
ASTM A1003/A1003M Structural Grade 50 (340) Type H, ST50H (ST340H): 50ksi (340MPa) minimum yield strength, 65ksi (450MPa) minimum tensile strength, 68mil minimum thickness (14 gauge, 0.0713” design thickness) with ASTM A653/A653M G90 (Z275) hot dipped galvanized coating.

Load Table Notes

  • StiffClip LS resists axial tension and ocmpression loads.
  • Allowable design loads may be calculated based on the section properties shown above.
  • Lengths greater than 20″ incorporate a stiffening lip to increase compressive strength.
  • For powder actuated fasteners, fasten within 3/4″ from the angle heel centerline of the 1-1/2″ leg.
