DriftTrak® DTSLB

DriftTrak® DTSLB is available to accommodate vertical deflection and lateral drift requirements. VertiClip® SLB’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.

Value

  • 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

  1. Fastener Pattern 1 replicates a condition of out-of-plane wind or seismic force with no vertical live load deflection and full in-plane drift.
  2. Fastener Pattern 2 replicates a condition of out-of-plane wind or seismic force with full vertical live load deflection and full in-plane drift. 

Note: Allow a minimum of 0.875" from the structure to the inside flange of the bypassing stud to allow for track attachment.
One row of bridging is recommended at a maximum distance of 12" from DriftTrak to resist torsional effects.

1 For LRFD Design Strengths refer to ICC-ESR-2049.

  • Load tables reflect horizontal loads (F2).
  • Design loads are for attachment of DriftTrak® DTSLB 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® DTSLB for attachment to stud. If loads justify use of a third screw, TSN will provide 3 slots, 3 step bushings and 3 screws with each clip.
