You will need support for any stone countertop that extends past the cabinetry by 12” or more; this support is achieved with stealth braces.
What are stealth braces?
Stealth braces are used to support your countertops for your island, peninsula, bar overhangs and for half walls, with no visible kicker or expensive corbels. They are made out of steel. They come in a variety of lengths; the depth of your overhang will determine the brace size you will need.
Are there different types of stealth braces?
Yes, but the most commonly used stealth brace is a hidden brace or the Speedbrace Stealth HD brace.
What is the proper load-bearing capacity for stealth braces?
They must always be used in pairs, with even load distribution. It is important to research which screws are best to use with your materials. Two stealth braces will support up to 300 pounds of weight, while Speedbrace Stealth HD braces can support over 500 pounds.
How are they attached?
If you are attaching them yourself you will need a few things to get started:
When you’re ready to attach your stealth braces, start your first brace 3”-6” from each end of your Island or bar area. Space each brace 16”-20” apart. They must be properly flush mounted and secured with screws to a wall stud or notched into the top of your cabinetry.
The side of the brace that is being secured with screws should always be ⅛” lower than the brace side supporting the stone, this will ensure that the stone is resting on the brace properly.
Here is a great short video that explains how to attach hidden braces on your island.
Who attaches the stealth braces?
If you are purchasing new kitchen cabinets, your cabinet installer should install them for you. Some countertop companies will install them, but not all…so be sure to check with them first, before you schedule your countertop installation.
