StiffClip® FS

StiffClip FS

StiffClip® FS series connects wall studs for a vertical uplift load transfer through the floor system. StiffClip FS resists tension forces only. The allowable design load table shown below is based on the use of StiffClip FS only. Number of fasteners used is based on fastener manufacturer’s allowable load data.


  • Mill certified 50ksi steel
  • Guide holes for attachment to wall studs (0.172” dia.)
  • Structurally load tested
