Product Information
TSN_DriftClipDSLS_3-Slot_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 DSLS 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. A minimum of 3.5" of DSLS is required for attachment to steel structure and a minimum of 6" is required for attachment to concrete structure.

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

Nomenclature

DriftClip DSLS is classified by multiplying stud depth by 100, followed by length.

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

* 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.
*** Three screws & step bushings are available for attachment to stud in 6" sizes and higher. Specify that 3 slots are needed when placing order.

Notes:

  • Design loads are for attachment of DriftClip DSLS to stud only. Load tables reflect horizontal loads (F2)
  • Attachment to structure engineered by others. As a design reference, follow ICCESR- 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.
  • One row of bridging is recommended at a maximum distance of 12" from DriftClip to resist torsional effects.
  • Return lip added for clips longer than 20".
  • DriftClip DSLS 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.

1 For LRFD Design Strengths for DSLS600-12 and DSLS600-15 refer to ICC-ESR-2049.
