## Overview

Winker’s 4-pack heavy-duty metal L brackets (12" x 6" x 2.5") provide robust, reliable support for countertops with overhangs from 12" to 16".

## Description

The advantage of our countertop bracket is as follows: Support – and strengthen your granite countertops, so you avoid potentially costly and dangerous breaks. HIDDEN - They provide a more spacious and open looking environment. Robust – Most of our brackets are made from 1/2" steel and have multiple mounting points. Safe – our mounts are directly attached to your knee/pony wall and offer a strong and sturdy structure on which your granite countertop can rest. Thin – no claws or suspenders for you or your guests to hit your knees on. Easy to install. Learn how to properly install our brackets by following our easy-to-follow tutorials. Inexpensive - usually much cheaper than Corbels. What length granite bracket do you need? Usually the bracket is the same length as the overhang. When the overhang is 12 inches, the length of the bracket should encompass the width of the knee wall. In most cases, the knee wall is 10.2 cm wide. The overhang plus the knee wall = 40.6 cm. Granite brackets should be positioned 7.6 - 10.2 cm from the edge of the granite slab to ensure they are not visible. So - 16" - 4" = 12" staples. If your knee wall consists of 2 x 6s, then make sure you adjust your size to accommodate the additional 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.
