Manufacturer's Product Description

VertiClip
SLB connects exterior curtain wall studs, bypassing the building structure, while allowing for vertical deflection of the structure up to 2” (1” up and 1” down). 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. VertiClip SLB eliminates flange-loaded, friction-fit clips, which do not address web-crippling. Allowable loads are based on use of two #12 screws for attachment to stud (provided by TSN)
An ICC-ES Evaluation Report for VertiClip SLB600 is available.
A Los Angeles Research Report for VertiClip SLD, SL, SLB, SLS, and SLT Series is available. Refer to LARR #25631.
Material Composition
ASTM A653/A653M, Grade 50 (340), 50ksi (340 MPa) minimum yield strength, 65ksi (450 MPa) minimum tensile strength, G-90 (Z275) hot-dipped galvanized coating. Material thickness = 68mil (14 gauge, 0.0713” design thickness).
The attachment of VertiClip to the primary structure may be made with a PAF or weld and is dependent upon the base material (steel or concrete) and the design configuration.
Allowable load tables incorporate eccentric loading of fasteners. Values with welded connection may increase.
Note:
Fasten within ¾” from the angle heel (centerline of the 1½” leg) to minimize eccentric load transfer.
Fasteners attaching clip to structure should be installed symmetrically around the center line of the clip. The allowable load of the clip may be reduced if fasteners are not installed symmetrically.
Guide holes in the 1½” leg measure .172” in diameter
Deflection requirements greater than 1” up or down are available.
VertiClip SLB series is designed to support horizontal loads and should not be used in axial-load-bearing wall construction.
