This
CRL Z-Series Square Type Radius Base Glass Clamp (SKU: Z712BS) is engineered for 1/2" (12 mm) glass. Available in zinc or stainless steel, this radius-base Z-clamp provides secure, low-profile mounting for partitions, railings, mezzanines and windbreaks where a 2" (51 mm) diameter round tubing attachment is required.
For securing the Z-clamp to thin-wall tubing (less than 1/8"), use CRL Socket Head Cap Bolt
ZB0LT and Rivet-Nut
ZRNUT. Drill a 17/32” (13.5 mm) hole, then install the rivet-nut using the 34604 Heavy-Duty Thread Insert tool with the 34618 5/16” mandrel and nosepiece.
NOTE: A 9/16" (13.52–14 mm) notch is required if using the included steel pin for additional glass support.
