ClarkDietrich FastClip Slide Clip deflection clips are used to attach exterior curtainwall 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. FastClip 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.
