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.
