No-Drill Glass Shelf Clamps are made of solid brass with a beautiful chrome or gold plated finish. 3/8" Version is 25/32, which is 1/32 over 3/4 inch Nylon set screws secure the glass, so absolutely no glass drilling is required. The version for 1/2 inch glass is #1222 and it's 15/16 inch diameter.
Maximum shelf protrusion from the wall is 5 inches (125 millimeters). The Shelf Clamps are also suitable for use with small acrylic or wood shelves.
