DriftClip® DSL

DriftClip® DSL is available to accommodate vertical deflection and lateral drift requirements at head of wall. Step Bushings pre-installed in vertical slots allow up to 2” vertical deflection (1” up and down). Horizontal slots accommodate 2” lateral drift (1” left and right -- in plane), with Step Bushings also preinstalled through the manufacturing process. Load tables are provided for attachment to stud. If more than 2” lateral drift is required, contact TSN engineering for more information.

DriftClip DSL Dimensions

Nomenclature

DriftClip® DSL is classified by multiplying stud depth by 100.

Example: 4” stud
Designate: DriftClip® DSL400.

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

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

  • Load tables reflect horizontal loads (F2) with 2 #12 screws.
  • Design loads are for attachment of DriftClip® DSL 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 DriftClip® DSL 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. 
Fastener Patterns
 DriftClip DSL Fastener Pattern 1  DriftClip DSL Fastener Pattern 2
Load Direction
DriftClip DSL-Load Direction 

Steel: ASTM A653/A653M, Grade 50 (340), 50ksi (340MPa) minimum yield strength, 65ksi (450MPa) minimum tensile strength, G90 (Z275) hot-dipped galvanized coating. Standard DSL thickness is 97mil (0.1017” design thickness).

The attachment of DriftClip to the primary structure may be made with a PAF, screw/bolt anchors or weld and is dependent upon the base material (steel or concrete) and the design configuration, and is the responsibility of the Structural Engineer of Record. The step bushing is optimized for use of a 1/4" - 20 fastener.
