This was a glass railing we did in their Rancho Santa Fe area. It is all 1/2 inch tempered glass with flat polished edges installed using a CR Lawrence aluminum base shoe channel. The channel was wrapped With a satin anodized cladding. We also installed a certain anodize we also installed a Satin Anodized low profile top rail to match. The aluminum base shoe was installed prior to the tile so that they could tile up to it and recess part of the base shoe. This is a very nice glass railing that allows them to enjoy their view with minimal obstructions
