VertiClip® SLT

VertiClip® SLT and SLT(L) slide clips connect exterior curtain wall studs, bypassing the building’s structural concrete slab or structural steel frame, while allowing for a vertical deflection of the structure of 1” (½” up and down for SLT) and 1.875” (0.938” up and down for SLT(L)). VertiClip’s unique design provides both an anti-friction and anti-seizure connection between the clip and stud web surface thereby preventing a transfer of vertical forces into curtain wall framing, which is not engineered to support axial loads. Allowable loads are based on use of #12 screws for attachment to stud (provided by TSN).

  • VertiClip® SLT is available in a length of 9 ½”.
  • VertiClip® SLT(L) is available in lengths of 12”, 15”, and 18”.
  • Determine length by adding stud + offset + 3” (for steel, or 5.5” for concrete) and selecting the next largest size.

Load Direction

VertiClip SLT Load Direction

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.

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.
