DriftTrak® DTSL

DriftTrak® DTSL is available to accommodate vertical deflection and lateral drift requirements. VertiClip® SL’s, with Step Bushings pre-installed in vertical slots, allow up to 2” vertical deflection (1” up and down). Clips are manufactured to fit into the DriftTrak® and provide free lateral movement of the structure. DriftTrak® is available in 12’ lengths. DriftTrak® DTSL does not provide wall closure. A top track will be required for closure of the wall assembly.

  1. Fit DriftTrak® into top track and secure to deck with approved fastener.
  2. Twist clip into place within DriftTrak®. Ensure stiffener is in place prior to installation.
  3. Fasten to stud using provided screws through Step Bushings.

Note: Allow a minimum of 0.875” from the structure to the top of the stud to allow for the attachment of DriftTrak inside the standard track.

  • Load tables reflect horizontal loads (F2).
  • Design loads are for attachment of DriftTrak® DTSL to stud only.
  • Attachment to structure engineered by others.
  • Allowable loads have not been increased for wind, seismic, or other factors.
  • Two #12 screws are provided with each DriftTrak® DTSL for attachment to stud.
