Product Overview

The CRL Z-Series Square Type Flat Base Glass Clamp is specifically designed for use with glass that is 1/2" (12 mm) thick. These clamps, made from either zinc or stainless steel, provide an ideal solution for various applications such as partitions, railings, and windbreaks.

To secure the Z-Clamp to thin wall tubing (less than 1/8"), use CRL's ZBOLT Socket Head Cap Bolt and ZRNUT Rivet Nut. During installation, drill a 17/32" (13.5 mm) hole, then install the Rivet-Nut using a Heavy-Duty Thread Insert tool and a 5/16" Mandrel and Nosepiece. Additionally, please note that a 9/16" (14.3 mm) hole is required if using the steel pin included with the clamp for additional glass support.
