DriftClip® DSLB

DriftClip DSLB

US Patent #6,612,087
 

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.

Product Information
DriftClip_DSLB_Application

Material Composition

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 DSLB to the primary structure may be made with PAFs, screws, or bolt anchors depending on the base material (steel or concrete) and the design configuration.  The step bushings used for attachment to structure are designed for use with ¼" maximum diameter fasteners.  Designing this connection is the responsibility of the Structural Engineer of Record, and a minimum of two fasteners must be used.

  1. Attach DriftClip DSLB to structure with specified fasteners through step bushings.
  2. Attach to stud with #12 provided screws through step bushings.

Nomenclature

DriftClip DSLB is classified by multiplying stud depth by 100.*

Example: 6” stud
Designate: DriftClip® DSLB600

* Parts with the designation “-CA” on the end of the part name includes a special bushing available to allow connection to the side of the concrete slab using two ¼” concrete screw anchors.
** If more than 2” lateral drift is required, contact TSN engineering.
*** One row of bridging is recommended at a maximum distance of 12” from DriftClip to resist torsional effects.

Notes:

  • Design loads are for attachment of DriftClip DSLB to stud only.
  • Attachment to structure engineered by others. 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.
  • Allowable loads have not been increased for wind, seismic, or other factors.
  • #12 screws are provided with each step bushing for attachment to stud. Load requirements don't always justify use of a third screw.
  • DriftClip DSLB allows up to 2" of vertical deflection (1" up and 1" down), and 2" lateral drift (1" left and 1" right in plane). Deflection requirements greater than 2" lateral drift are available.
  • 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.
* Three screws are not applicable to DriftClip DSLB362.
