## Overview

The Winker Countertop Support Bracket 3 Pack offers heavy-duty, 0.4" thick steel L brackets measuring 12" x 6" x 2.5", designed to support countertop overhangs between 12" and 16". Each pair can hold up to 300lbs, making them ideal for quartz, granite, wood, concrete, and laminate surfaces.

## 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.

Review: these are heavy duty brackets
Review: These are so strong and definitely feel strong enough to hold up the weight its rated for. All depend on how you fix them. Metal is soft enough to easily drill the holes large to allow larger fixings, as I used M8 bolts and kemfix to attach to the wall to support worktop

### ⭐⭐⭐⭐⭐ Review
*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.
