FastClip™ Slide Clip (FCSC-HD) w/Anchor Holes

Vertical building movement up to 3"

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.

Proprietary 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.


To attach the clip to the cold-formed steel framing stud, three Proprietary Deflection Screws, shall be driven through the slotted holes and positioned to allow for the appropriate building deflection. Attachment to the structure concrete slab can be made with 1/2" bolt anchors.  Anchor connection design and edge distance requirements must be approved by a design professional before installation.
