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.

DriftClip^® DTSLB has been issued an
ICC-ES Report. Click here to access
ICC-ESR-2049 (pdf).

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

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

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
