## Description

The benefit of our countertop support bracket is as following: SUPPORT - and strengthen your granite countertops helping you avoid potentially costly and dangerous breaks. HIDDEN - They provide a more spacious and open looking looking environment. TOUGH - Most of our brackets are made of 1/2 inch steel and have multiple mounting points. SAFE - Our brackets mount directly to your knee / pony wall providing a strong and stable structure for your granite countertop to rest on. THIN - no corbels or braces for you or your guests to hit their knees on. EASY - to install. Learn how to properly install our brackets by following our easy to understand tutorials. INEXPENSIVE - typically much less expensive than corbels. What length granite bracket will you need? Typically the bracket will be the same length as the overhang. If the overhang is 12 inch, the length of the bracket should include the width of the knee wall. In most instances the knee wall is 4 inches wide. The overhang plus the knee wall = 16 inches. Granite Brackets should be set three - four inches back from the edge of the granite counter top to insure they are hidden from view. So - 16 inches - 4 inches = 12 inch brackets. If your knee wall is made from 2 x 6s then be sure to adjust your size to accommodate the extra 2 inches.
