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.

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.

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:
1. Design loads are for attachment of DriftClip DSLS to stud only. Load tables reflect horizontal loads (F2).
“2. Attachment to structure engineered by others. As a design reference, follow ICC-
ESR-3332 for allowable loads for screw fasteners of ¼”- 20 size with various plate
thickness”
3. Allowable loads have not been increased for wind, seismic, or other factors.
“4. #12 screws are provided with each step bushing for attachment to stud. Load
requirements don’t always justify use of a third screw.”
“5. One row of bridging is recommended at a maximum distance of 18” from DriftClip
to resist torsional effects.”
6. Return lip added for clips longer than 20”.
“7. 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.”
