DriftClip® DSLB

DriftClip® DSLB 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.

DSLB Dimensions

Nomenclature

DriftClip DSLB is classified by multiplying stud depth by 100.

Example: 6” stud
Designate: DriftClip DSLB600.

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 (p33).
* Three screws are not applicable to DriftClip DSLB362.

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

Load Direction
DriftClip DSLB-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.

As a design reference for the structure attachment, follow ICC-ESR-3332 for allowable loads for screw fasteners of ¼”- 20 size with various plate thickness.
