This CRL Z-Series Square Type Flat Base Glass Clamp is designed to be used on glass thickness of 3/8" (10 mm). The flat base allows for installation onto Square Tubing or other flat surfaces. Material is constructed of Zinc Casting with a Powder Painted finish. The Clamps include an optional Steel Pin for additional weight support. These Clamps are the perfect solution for partitions, railings, windbreaks and countless other projects.

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. For installation, drill a 17/32” (13.5 mm) hole, then install the Rivet-Nut using 34604 Heavy-Duty Thread Insert tool and 34618 5/16” Mandrel and Nosepiece.

1/2" (12 mm) hole is required if using the steel pin (included with the clamp) for additional glass support.
