## Overview

The Solid Heavy Duty Steel Hidden Countertop Support L-Bracket is a 15-inch, American-made steel support designed for DIY projects. It features a sleek, invisible design that eliminates knee-knocking, ensuring comfort and safety. With a durable construction and a Limited Lifetime Warranty, this bracket is the perfect solution for securing your countertops while maintaining an open and inviting space.

## Description

For countertop installation mounted over a knee/pony wall, then into each stud on the knee/pony wall, to secure the weight of the countertop. If no knee/pony wall, then a 2x6 must be mounted inside the cabinet and the L Bracket attached spacing every 20". **Not for use in any other application than that listed. When determining the size: bracket is sized in length tip to tip horizontally; for example, a 9" bracket is 9" tip to tip horizontally. Do not include the 6" vertical piece when determining the size to order. Tip on determining length: stay away from outer edge of your countertop 3" and do not forget to add in the thickness of the knee wall, pony wall, or the 2x6 inside the cabinet. For example, only: a 12" countertop overhang, plus 4" knee wall, equals 16", minus 3" outer edge, would mean you would order a 13" L-Bracket. Made of ½" thick by 2 ½" wide American steel on the horizontal piece and the vertical piece [tang] is made of ¼" by 2 ½" x 6" long wide American steel powder coated. This is for one (1) bracket only

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Heavy duty
  

*by J***E on Reviewed in the United States on July 15, 2024*

Used for under our quarts countertops. Heavy duty

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Heavy duty bracket, unusual application
  

*by W***R on Reviewed in the United States on April 3, 2023*

I used these to float butcher block in our home office for the desk leaving the underside free of cabinets or legs and allowing free movement of our legs and feet. These do flex a bit, especially out near the end, but are generally very heavy duty and I am happy with the end result. Install is a bit tricky, the brackets I used all needed to mount at the same height but the screw holes weren't exactly the same from bracket to bracket so I matched each bracket to a Lazer level line and installed each as a unique piece instead of being able to use a template to predrill all the locations.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    worked well
  

*by C***S on Reviewed in the United States on November 6, 2023*

The shipper was great. The box was a little beat up and I think one piece fell out during shipping because I received only three of the four brackets I ordered. Upon notification the vendor had the replacement fourth one shipped to me immediately. Very good service.
