DriftClip® DSL
This drift slide angle is used to connect exterior cold-formed steel curtain wall studs to the slab at the head of wall, while allowing for 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
- 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, 97 mil, G90 cold-formed steel

Nomenclature:
DriftClip DSL is classified by multiplying stud depth by 100.*
Example:6” stud depth
Designate:<DriftClip® DSL600.
* 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.
*** Three screws & step bushings are present in 6″ sizes and higher. Refer to design requirements for required fastener quantity and placement. TSN provides #12 screws for each bushing for connection through step bushings to stud web.

DriftClip® DSL Applications
The attachment of DriftClip DSL 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.
Drift Connection at the Exterior Head of Wall
Installation Instructions
- Attach track to structure with required fasteners.
- Attach DriftClip DSL to structure with required fasteners through each Step Bushing.
- Attach DriftClip DSL to stud with provided #12 screws through each Step Bushing.

Notes:
- Design loads are for attachment of DriftClip DSL to stud only.
- Allowable loads have not been increased for wind, seismic, or other factors.
- DriftClip DSL 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.
- For LRFD strengths contact TSN technical services.
