Use granite countertop support brackets when overhanging stone counters. Considering that granite, marble, and limestone can have overhangs weighing hundreds of pounds, and considering how brittle granite countertops can be, granite support brackets are imperative. Quartz countertops often do not need these brackets.
Granite supports can be either functional, decorative, or both depending on your granite countertop installation. And unlike laminate countertops that do not require supports, natural stone countertops require some thought and understanding of why and how they will be used. It's best to let an expert such as your granite fabricator determine the need.
Many builders and designers use decorative brackets to support granite tops and offset the downward pressure from people pushing or leaning on a cantilevered top. These brackets can be a real pain since you tend to hit your legs on them. They may look rather unattractive too.
A good alternative to decorative granite supports is to place a piece of flat 1/8 inch thick plate steel screwed and bolted to the top of the wall. You can holes in the plate for screws. For granite, use silicone to adhere the counter top to the plate. The steel plate also protects the stone from cracking.
If your intention is to use corbels as a means of support underneath a countertop, the depth of the corbel you choose must be at least 1/2 the depth of the overhang which it will support . . . Read More
