DriftTrak® DTSL

DriftTrak DTSL

US Patent #7,503,150
 

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.

Value

  • Positive, load rated mechanical attachment to stud
  • Drift amount limited only to stud spacing and wall termination
  • Step Bushings & Stiffener pre-installed for accurate placement
  • Rated screws provided for attachment to stud web
  • Grooves in 1” leg pass over fastener heads

Material Composition

Clip Material:  ASTM A1003/A1003M Structural Grade 50 (340) Type H, ST50H (ST340H): 50ksi (340MPa) minimum yield strength, 65ksi (450MPa) minimum tensile strength, 68mil minimum thickness (14 gauge, 0.0713” design thickness) with ASTM A653/A653M G90 (Z275) hot dipped galvanized coating.

Track Material:  ASTM A1003/A1003M Structural Grade 50 (340) Type H, ST50H (ST340H): 50ksi (340MPa) minimum yield strength, 65ksi (450MPa) minimum tensile strength, 97mil minimum thickness (12 gauge, 0.1017” design thickness) with ASTM A653/A653M G60 (Z180) hot dipped galvanized coating.

  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.

Notes:

  • Design loads are for attachment of DriftTrak DTSL to stud only. Load tables reflect horizontal loads (F2).
  • Attachment to structure engineered by others.
  • Allowable loads have not been increased for wind, seismic, or other factors.
  • Two (2) #12 screws are provided with each DriftTrak DTSL for attachment to stud.
  • Clips are manufactured to fit into the DriftTrak and provide up to 2" of vertical deflection (1" up and 1" down), and free lateral movement of the structure.
  • 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.
  • One row of bridging is recommended at a maximum distance of 18" from DriftTrak to resist torsional effects.
  • DriftTrak DTSL does not provide wall closure. A top track will be required for closure of the wall assembly.
