ClarkDietrich FCSC-HD 68mils (14ga) is used to attach exterior curtain-wall studs to the building concrete structure and provide for vertical building movement independent of the cold-formed steel framing.
FastClip Deflection Screws are provided with each clip for attachment to the wall studs and allow for 3" vertical deflection (1-1/2" up and down) to ensure friction-free sliding. A 5/8" hole in the short leg of the clip allows for a 1/2" concrete anchor to be attached to the slab. (2) 3/8" holes allow for 1/4" anchors.
