DriftClip® DSLS
This drift slide angle strut is used to connect exterior cold-formed steel curtain wall studs to structural steel frame when large stand-off conditions exist, bypassing the primary structure, while allowing for up to 2” vertical deflection (1” up and down) and 2” lateral drift (1” left and right-in-plane). TSN’s patented Step Bushing Technology® provides an anti-friction and anti-seizure connection between the clip and both the stud web surface & track.
Features
- ICC-ES Approved, report #ESR-2049
- If more than 2” lateral drift is required, contact TSN engineering for a custom solution
- Load-rated positive mechanical attachment at each stud
- Patented Step Bushing Technology provides friction-free motion for smooth vertical deflection
- Eliminates loose friction-held assemblies, heavy deep-leg track, & top row of wall bridging/strapping
- Load-rated #12 screws provided for vertical deflection connection to stud web
- Manufactured with certified, 50ksi, 97mil, G90 cold-formed steel

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

DriftClip® DSLS Applications
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.
Drift Steel Frame Bypass Connection
Installation Instructions
- Attach DriftClip DSLS to structure with specified fasteners through step bushings.
- Attach to stud with #12 provided screws through step bushings.
Allowable Loads
Table Notes:
- Design loads are for attachment of DriftClip DSLS to stud only.
- Allowable loads have not been increased for wind, seismic, or other factors.
- DriftClip DSLS allows up to 2″ of vertical deflection (1″ up and 1″ down), and 2″ of lateral drift (1″ left and 1″ right) in plane. Deflection requirements greater than 2″ of lateral drift are available.
- #12 screws are provided for each step bushing attachment to studs. Load requirements do not always require the use of a third screw.
- Attachment of structure to be engineered by others. As a design reference for the structure attachment, reference AISI S100 or screw manufacturers published data for allowable loads for screw fasteners of 1/4″-20 size with various plate thicknesses.
- One row of bridging is recommended at a maximum distance of 18″ from DriftClip to resist torsional effects.
- Return lip added for clips longer than 20″.
- For LRFD strengths contact TSN technical services.
