DriftClip® DSLS Bypass Structure

  Product Application  

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.

  Material Composition  

Steel: ASTM A653/A653M, Grade 50 (340), 50ksi (340MPa) minimum yield strength, 65ksi (450MPa) minimum tensile strength, G-90 (Z275) hot-dipped galvanized coating.
Standard DSLS thickness is 97mil (0.1017” design thickness).

The attachment of DriftClip to the primary structure 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.

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

An ICC-ES Evaluation Report for DriftClip DSLS is available.

DriftClip DSLS 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.
DriftClip DSLS Features
  • Positive, load rated mechanical attachments
  • Manufactured from mill-certified, 50ksi steel
  • Step Bushings pre-installed for accurate placement
  • Rated screws provided for attachment to stud web

  DriftClip DSLS Installation 

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

Allowable (Unfactored1) Loads

Fastener Pattern 1 replicates a condition of out-of-plane wind or seismic force with no vertical live load deflection or in-plane drift.
 
Fastener Pattern 2 replicates a condition of out-of-plane wind or seismic force with full vertical live load deflection and full in-plane drift.

     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
