DriftTrak® DTSLB Bypass Slab

 
Product Application

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.

Material Composition

Steel: ASTM A653/A653M, Grade 50 (340), 50ksi (340MPa) minimum yield strength, 65ksi (450MPa) minimum tensile strength, G-90 (Z275) hot-dipped galvanized coating (clip only), G-60 (Z180) hot-dipped galvanized coating (track).

Standard DTSLB clip thickness is 68mil (0.713” design thickness). Track thickness is 97mil (0.1017” design thickness).

Note: Allow a minimum of 0.875” from the structure to the inside flange of the bypassing stud to allow for track attachment.

DriftTrak DTSLB Nomenclature

DriftTrak DTSLB is classified by multiplying stud depth by 100.

Example: 6” stud
Designate: DriftTrak DTSLB600.

One row of bridging is recommended at a maximum distance of 12” from DriftTrak to resist torsional effects.

DriftTrak DTSLB 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

DriftTrak DTSLB Installation
  1. Attach DriftTrak to structure at required spacing with specified fasteners.
  2. Twist clip into track. Ensure stiffener is in place prior to installation into track.
  3. Attach clip to stud with provided screws through Step Bushings.

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.

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.

     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.
