DriftTrak® DTSLB

DriftTrak DTSLB

US Patent #7,503,150
 

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.  Standard DriftTrak DTSLB clips have notches to facilitate horizontal movement of the clips inside the track over fastener heads. If this feature is not needed (i.e. welded track to structure or no drift requirements), use DriftTrak DTSLB-HD clips without notches for greater F2 outward load capacity. Locking Angle DT-LA is available to lock the horizontal movement of the wall panel after installation for cases of no drift requirements.  DriftTrak is available in 12’ lengths.

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

Product Information
DriftTrak DTSLB Application

Material Composition

DTSLB 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.

DTSLB-HD Clip and 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. 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.

Nomenclature

DriftTrak DTSLB is classified by multiplying stud depth by 100, followed by "HD," based on F2 strength required.  Refer to load tables.*

Example: 6" stud depth, with an outward load (F2) of 1,000 lbs
Designate: DriftTrak® DTSLB600-HD

* Clips and track sold separately.
** Notches are standard in DriftTrak DTSLB.  For greater F2 outward load capacity, use DTSLB-HD clips without notches.  Refer to Allowable Load Table.

Notes:

  • Design loads are for attachment of DriftTrak DTSLB 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.
  • #12 screws are provided with each step bushing for attachment to stud. Load requirements don't always justify use of a third screw.
  • 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 inside flange of the bypassing stud to allow for track attachment.  Standard offset of stud from the open face of the track should not exceed 1.25".
  • One row of bridging is recommended at a maximum distance of 18" from DriftTrak to resist torsional effects.

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