FastClip™ Slide Clips (FCSC)

Provide for vertical building movement up to 3"

ClarkDietrich FastClip™ Slide Clip deflection clips are used to attach exterior curtain-wall studs to the building structure and provide for  vertical building movement independent of the cold-formed steel framing.

A FastClip deflection clip installs quickly with screws or powder-actuated fasteners, and provides adjustable standoff to ensure a plumb wall plane. Proprietary Deflection Screws are provided with each clip to ensure friction-free sliding. Each clip is also embossed with fastening patterns to ensure accurate placement of fasteners. 

  • Vertical movement up to 3" (1-1/2" up and 1-1/2" down).
  • 3-1/2" FastClip™ permits up to 1" of standoff from the primary frame.
  • 5-1/2" FastClip™ permits up to 2" of standoff from the primary frame.
  • Proprietary Deflection Screws (included) provide frictionless slip connection.
  • U.S. Patent No. 6,688,069

Connections to the building can be made with screws, powder-actuated fasteners or drill-in concrete anchors. Mechanical fasteners shall be located on the embossed marks given on the scored line of the 1.5" flange. Two or three Proprietary Deflection Screws (based upon clip size) are used to attach the clip to the cold-formed steel framing. Screws shall be driven through the slotted holes and positioned to allow for the appropriate building deflection.

Proprietary Deflection Screws

Many of the ClarkDietrich deflection clips include our Proprietary Deflection Screw that has been specifically designed to provide friction-free deflection. These fasteners eliminate drag, binding or resistance that can often occur with common fasteners.
