MasterClip® VLB connects exterior curtain wall studs, bypassing the building structure. Its unique configuration allows the option for a rigid connection to resist horizontal and vertical loads, or for vertical deflection of the structure up to 2” (1” up and 1” down). MasterClip’s integrated break-away bushings provide 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. MasterClip VLB eliminates flange-loaded, friction-fit clips, which do not address web-crippling. Three #12 screws for attachment to stud through the integrated bushings are provided by TSN.

Material Composition
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 MasterClip® 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.
