VertiTrack® VTX
VertiTrack® VTX deflection track connects exterior curtain wall studs at head of wall to the building frame while allowing forvertical deflection of the structure of up to 1½” (¾” up and ¾” down). A VertiClip® SL is pre-assembled at 16”o.c. or 24”o.c. (or any pre-required stud spacing). 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 VertiTrack VTX over friction-fit track assemblies minimizes liability through the utilization of positive mechanical attachments to the web of the stud. Value

Nomenclature VertiTrack® is manufactured in 12 ft. lengths. VertiTrack® is designated by type (VTX), followed by stud depth in inches multiplied by 100 and stud spacing. Example: 6” deep stud, 16” on center |
VertiTrack® VTX loads are the same as VertiClip® SL loads.
Clip Material: 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.
Track Material: ASTM A1003/A1003M Structural Grade 33 (230) Type H, ST33H (ST230H): 33ksi (230MPa) minimum yield strength, 45ksi (310MPa) minimum tensile strength, 43mil minimum thickness (18 gauge, 0.0451” design thickness) with ASTM A653/A653M G60 (Z180) hot dipped galvanized coating. Track leg length = 1.5”.
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.
