DriftTrak® Post-Tensioned Slab
As with DriftTrak Bypass this drift slide track incorporates the studded DriftTrak member with the DriftTrak DTSLB slide angle or DriftTrak DTLB rigid angle to connect exterior cold-formed steel curtain wall studs to the primary structure while bypassing the slab. DriftTrak Post-Tensioned Slab however, can be integrated directly into a post-tensioned slab before pouring, saving the time and expense of installing DriftTrak with lifts after the concrete slab has been poured.
Features
- Locking Angle DT-LA is available to lock the horizontal movement of the wall panel after installation for cases of no drift requirements.
- DriftTrak DTH-PTS is available in 12’ lengths.
- Load-rated positive mechanical attachment at each stud
- Patented Step Bushing Technology provides friction-free motion for smooth vertical deflection
- Eliminates loose friction-held assemblies, heavy deep-leg track, & top row of wall bridging/strapping
- Load-rated #12 screws provided for vertical deflection connection to stud web
- Track DTLB-PTS, & DTSLB-PTS manufactured with certified, 50ksi, 97mil, G90 cold-formed steel
- DTSLB manufactured with certified, 50ksi, 68mil, G90 cold-formed steel

Nomenclature: The DriftTrack Headed Stud comes in 12′ lengths. To specify DriftTrak, list “DTH,” followed by the length. The assembly requires the member (DTH-12) and the connector (DTSLB/DTLB). 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: DTH-12 & DTSLB600-HD
* Clips shown are left versions of DriftTrak DTLB-PTS & DTSLB-PTS. Right side versions are available as standard parts.
** Clips and track sold separately.
Material Composition
Headed Stud Material: ASTM A29/A108, Grades 1010 through 1020 or equivalent, 45ksi (310MPa) minimum yield strength, 55ksi (380MPa) minimum tensile strength, ⅜” diam. x 3 ⅛” length with ¾” head diameter.
Clip Material: DriftTrak Headed Stud – PTS can be used with DTSLB-PTS and DTLB-PTS clips: 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 G90 (Z275) hot dipped galvanized coating.

DriftTrak® Post-Tensioned Slab Applications
The unique design of DriftTrak Post-Tensioned Slab allows it to be installed prior to pouring the slab. This reduces installation cost as well as safety for installers.
Headed Stud Embedded into a Post-Tensioned Slab for Curtain Wall Slab Bypass as a Drift Connection with No Vertical Deflection
Headed Stud Embedded into Slab for Curtain Wall Slab Bypass as a Drift & Vertical Deflection Connection
Installation Instructions
Step 1: Insert DTH-PTS inside concrete slab form prior to pouring concrete.
Step 2: Adjust DTH-PTS vertically per design details. Block end to prevent concrete seepage.
Step 3: After concrete form is removed, twist clips into DTH-PTS track.
Step 4: Install stud panel and slide clips into place.
Step 5: Ensure stiffener is in place.
Step 6: Attach stud to clip with specified fasteners through guide holes.
Optional Step: To lock lateral movement, fasten DT-LA (Locking Angle) to DriftTrak components using #12 screws (not included). Locking is recommended at 4 ft. spacing or 3rd stud, max.
DriftTrak® Post-Tensioned Slab Allowable Loads:
Load Table Notes:
- Maximum tension on a single anchor should not exceed 1,600 lbs ASD. In tension and shear, the strength of the anchor itself should be considered. The weld does not need to be considered in tension or shear as the load table and 1,600 lb ASD tension maximum are inclusive of the strength of the welds.
- Designers must check headed stud tension and shear anchorage capacity in concrete per ACI 318 based on actual headed stud edge distance and concrete compressive strength. For more information, call TSN Technical Support at 1-888-474-4TSN.
- Allowable load tables incorporate eccentric loading of fasteners.
- Loads listed reflect force in a single direction. When multiple loads react on the connection, it is the responsibility of the designer to check the interaction of forces.
- Torsional effects are considered on screw group for F3 allowable loads. It is assumed that all of the torsional moment is taken by the connection to the stud.
- Design loads are for attachment of DriftTrak to stud and DriftTrak itself. Load tables reflect horizontal loads (F2) and vertical loads (F3)
- Allowable loads have not been increased for wind, seismic, or other factors.
- Clips are manufactured to fit into the DriftTrak and provide a rigid/slip connection to the stud, and free lateral movement of the structure.
- One row of bridging is recommended at a maximum distance of 18” from DriftTrak if no other stud lateral restraint is present.
