CRL's Vertical Panel Connectors are the ideal product for hanging 1/4" to 3/8" (6 to 10 mm) mirrors or glass panels in a high moisture environment where clamping on the edges of the glass is not the most secure method. The Panel Connectors are also the choice when Cables are designed to be installed behind the panel. Glass or panel fabrication requires a minimum 1/4" (6 mm) diameter hole, and can require a 3/8" (10 mm) diameter hole for 3/8" (10 mm) thick tempered glass. Each Panel Connector has a maximum weight capacity of 20 lbs. (9 kg) for 1/4" to 5/16" (6 to 8 mm) panels, and 10 lbs. (4.5 kg) for 3/8" (10 mm) panels.
