DriftClip® DSLS

DriftClip® DSLS is available to accommodate vertical deflection and lateral drift requirements. 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 pre-installed during 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 DSLS Dimensions

Nomenclature

DriftClip® DSLS is available in a variety of lengths (shown in the chart at right), and classified by multiplying stud depth by 100 followed by length.

Example: 6” stud, 15” length
Designate: DriftClip® DSLS600-15.

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)
  • Design loads are for attachment of DriftClip® DSLS 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® DSLS for attachment to stud. If loads justify use of a third screw, TSN will provide 3 slots and 3 screws with each clip

Load Directions
 DriftClip DSLS-Load Direction

Steel: 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.

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 Bushings used for attachment to structure are designed for use with ¼” - 20 size fasteners. A minimum of two fasteners should be used for attachment to structure. Minimum of 3.5" of DSLS required for attachment to steel structure, 6.0" minimum for concrete structure.

  • As a design reference, follow ICBO-ES Report #4780 for allowable loads for screw fasteners of ¼”- 20 size with various plate thickness.
