VertiClip® SLT

SLT
US Patents #5,467,566 & #5,906,080

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).

Value

  • Friction-free movement
  • Certified material
  • Eliminates untested “scabs” or shims

Product Information

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

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.

Notes:

  • VertiClip SLT series is designed to support horizontal loads and must not be used in axial-load-bearing wall construction.
  • Allowable loads have not been increased for wind, seismic, or other factors.
  • #12 screws are provided with each Step Bushing.
  • VertiClip SLT & SLT(S) allow up to 2” of vertical deflection (1”up and 1” down).
  • VertiClip SLT(L) allows up to 1.875” of vertical deflection (0.938” up and 0.938” down)
  • VertiClip SLT(S) Recommended Allowable Loads are based on 4 #12 screws at the stud attachment and either front or rear fastener attachment at the structure respectfully.
  • Torsional effects are considered on screw group for F2 allowable loads. All torsion attributed to screws, none to the clip connection to structure.
  • VertiClip SLT is recommended to have for steel attachment a ½” minimum edge distance from fasteners and for concrete attachment a 2 ¼” minimum edge distance from fasteners.
