ClarkDietrich Fast Strut curtainwall connector employs the Fast Clip technology for curtainwall stud attachment and is commonly used when large stand-off conditions exist. Fast Strut products are available in standard lengths of 12-1/4" and 15-1/4" and custom lengths of up to 24" long to allow framing attachment well beyond the perimeter of the structural steel or when the spandrel beams are set back from the edge of the structure. Struts are attached to the underside of structural members with screws, welds, or powder-actuated fasteners. FastClip Deflection Screws are provided with each strut to ensure friction-free sliding. Each strut is also embossed with fastening patterns to ensure accurate placement of fasteners.
