This CRL Z-Series Square Type Radius Base Glass Clamp (SKU: Z712PS) is engineered for 1/2" (12 mm) glass and is available in zinc or stainless steel. Ideal for railings, partitions, windbreaks and mezzanine guards, this radius-base Z-clamp provides a secure, low-profile mounting solution for exterior and interior architectural glass applications.

For securing the Z-clamp to thin-wall tubing (less than 1/8"), use CRL’s ZB0LT socket head cap bolt and ZRNUT rivet-nut. 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 when using the included steel pin for additional glass support.
