What Are Countertop Support Brackets?
Countertop support brackets, also known as heavy-duty floating shelf brackets, are designed to support heavy countertop materials like stone, steel, or natural hardwood. There are many different designs of countertop support brackets for these materials. The most common are hidden countertop supports because they’re undetectable. They’re typically used for knee walls, breakfast bars, and reception counters. Low profile brackets are also popularly used for large overhangs on islands, wall hung counters, and vanities. Still, elevated countertop supports and countertop standoff brackets are popular in smaller spaces as these supports attach to the wall, cabinet base, or to the top of your counter, respectively, to create or elevate eat-in areas. Island legs are another type of countertop support brackets which support various countertop heights or large overhangs as well.
How to Install Countertop Support Brackets
Given the different types of countertop support brackets, there are two ways to install countertop support brackets. The first includes a hand saw, wood chisel, screws and screwdriver, and level.
- Measure, space out, and mark the appropriate mounting locations on your knee wall. You should start six inches inward from the edges. Space the bracket 18” to 24” apart.
- Identify and mark the T-Square two diagonal lines 2 and 9/16th” apart from the mounting location.
- Cut along each line ½” in depth using a hand saw.
- Remove all the material between the lines using a wood chisel to create a clean and level mounting channel. Clear away any excess chips or dust.
- Once cleared, place the support bracket in the mounting channel and affix it to the knee wall with the appropriate screws.
- Level the bracket in the knee wall.
The second way involves more complex tools, such as a router, router bit, and level. You’ll see some similar processes as with the other way, in addition to some slight differences as well.
- Measure, space out, and mark the mounting locations on the knee wall.
- Use a T-Square to mark the diagonal lines at the mounting locations.
- Work left to right, aligning the inner edge of a ¼ x 4” strip wood router guide with the horizontal line.
- Trim any excess wood out of the mounting surface with a Top Bearing Flush Trim router bit and ½” cutting depth until you have a clean and level channel to seat the bracket. Clear away any excess chips or dust.
- Once cleared, place the support bracket in the channel and affix it to the knee wall with the appropriate screws.
- Level the bracket in the knee wall.
Notably, brackets with side or back angles do not need a mounting channel, as the sheetrock covers them. It is easier to trim the rock and apply a sheetrock patch rather than create additional mounting points. Also, your knee wall must be stable to support the countertop. It might help to pre-drill the screw holes beforehand to prevent the studs from cracking.
