StiffClip® FS

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

Nomenclature

StiffClip FS is designated by the width of the strap in inches followed by strap thickness in mils.

Example: 16ga, 2¾” strap, 24” long
Designate: StiffClip® FS275-54-24

* Guide holes located 1/2″ from each end, with ⅜” edge distance at 2″ o.c. staggered for FS125 and 0.75″ edge distance at 2″ o.c. staggered for FS275. Additional guide holes for fasteners available upon request.
** Sizes shown in table are typical, but can vary. StiffClip FS is usually made to order. Contact TSN for additional pricing, quantity and order information

Material Composition

StiffClip® FS Applications

The unique design of MasterClip allows it to be installed either as a vertical deflection connection or a rigid connection.  Attachment to the primary structure may be made with a PAF, screw/bolt anchors, or weld and is dependent upon the base material (steel or concrete) and the design configuration.

Load Table Notes

  • Design loads are based on strap capacity only. StiffClip FS resists tension forces only.
  • Number of fasteners used is based on fastener manufacturer’s allowable load data.
  • Guide holes are located 1/2″ from each end, with 3/8″ edge distance at 2″ o.c. staggered for FS125 and 3/4″ edge distance at 2″ o.c. staggered for FS275.
  • Allowable loads have not been increased for wind, seismic, or other factors.
  • For LRFD strengths contact TSN technical services.
