Drift Rail and Clip (DRC) Deflection or Rigid

lateral building movement for deflection or rigid stud connections

ClarkDietrich Drift Rail 97mil (12ga) and Clip 97 mil or 68mil (12ga or 14ga) is a uniquely designed two-piece system that is used to attach curtain-wall studs to the building structure and allows for vertical and lateral movement or to be rigidly attached.  The system utilizes a C-Shaped Drift Rail and distinctively designed Drift Rail Clips that rotate into position for easy installation.  The multifaceted Drift Rail Clips use FastClip Deflection Screws for attachment to the wall studs and allows for 3" vertical deflection (1-1/2" up and down) and is also designed with 1/8" holes to rigidly attach wall studs.
