VertiClip® SL

VertiClip® SL connects the exterior curtain wall studs at head of wall to the building frame while allowing for vertical deflection of the structure up to 1½” (¾” up and down). VertiClip’s unique design provides both an anti-friction and anti-seizure connection between the clip and the stud web surface thereby preventing a transfer of vertical forces into curtain wall framing, which is not engineered to support axial loads. Use of VertiClip SL over friction-fit track assemblies helps protect liability through the utilization of positive mechanical attachments to the web of the stud. VertiClip SL is a component of VertiTrack® VTX, our preassembled deflection track. Allowable loads are based on use of two #12 screws for attachment to stud (provided by TSN).

Value

  • Load-rated positive mechanical attachment at each stud
  • Eliminates friction-held assemblies
  • Utilizes only certified, 50ksi steel
  • Step Bushings pre-installed for accurate placement
  • Load rated screws provided for each VertiClip
  • Meets all building code criteria
  • Adaptable for multiple configurations
  • Top of wall bridging or strapping is eliminated
  • Top track lightweight for easy handling (not a structural element, may be 20ga standard leg - Deep-Leg Track is not required)
  • Utilize clips for wall layout
  • Eliminates temporary screws

VertiClip SL Application

Note: Track thickness not limited to 20 gauge.
  1. Attach standard leg track to structure. Track will allow for alignment and closure.
  2. Fasten SL to top track at designed stud spacing with engineered fastener.
  3. Attach SL to wall stud with provided screws through Step Bushings.

 VertiClip SL Dimensions 

Nomenclature

To designate the proper clip on drawings, multiply stud depth by 100.  VertiClip SL is sized to match stud depth.

Example: 6” stud: Designate SL600.

Note:

  • SL (Clip is 14ga, 68mils)
  • Fasten within ¾” from the angle heel (centerline of the 1½” leg) to minimize eccentric load transfer.
  • Guide holes for attachment to structure are .172” in diameter for SL600 and .141" in diameter for SL362. Guideholes are not standard in other sizes.
  • Deflection requirements greater than ¾” (up and down) are available.
  • VertiClip SL series is designed to support horizontal loads and should not be used in axial-load-bearing wall construction.
  • Allowable loads have not been increased for wind, seismic, or other factors.
  • Two #12 screws are provided with each VertiClip SL.
  • If loads justify use of a third screw, TSN will provide 3 slots and 3 screws with each clip.

Load Direction

 

VertiClip SL Load Directions

ASTM A1003/A1003M Structural Grade 50 (340) Type H, ST50H (ST340H): 50ksi (340MPa) minimum yield strength, 65ksi (450MPa) minimum tensile strength, 68mil minimum thickness (14 gauge, 0.0713” design thickness) with ASTM A653/A653M G90 (Z275) hot dipped galvanized coating.

The attachment of VertiClip to the primary structure may be made with a PAF, screw/bolt anchors or weld and is dependent upon the base material (steel or concrete) and the design configuration.
