## 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.

### ⭐⭐⭐⭐⭐ Heavy duty product, very well made
*by M***M on 28 December 2025*

These brackets are extremely good quality. They are very heavy duty. We are using these brackets to support 12' x 16" x 2" black walnut shelves. I have no doubt these will support the weight easily. The welds are also done very good, as well as the coating/ finish. I did find that the screws provided for wall side did not fit the hole properly. I contacted the seller and they were extremely responsive and worked with me to get the correct screws. I have never dealt directly with a seller in China, and was very impressed with their willingness to help and make their customer happy. I will definitely purchase from them again. Great product and service.
