Do Need " Granite And Bar Top Overhang Support
The bracket will be mounted to the inside of the cabinet. Start by measuring your cabinet from the inside front wall (where the doors are) to opposite side of the cabinet (for our example we are saying this measurement is 22 inches).
Completely open space allowing room for chairs and legs.
Smooth edges, they can’t be seen and our legs don’t bump into them! The hidden island support brackets worked perfect. Will use on all my island and peninsula applications.We purchased new granite countertops for our kitchen. There are (2) overhangs on the countertop, one is a 7 foot long, 12″ overhang and then the end of the last base cabinet peninsula that is 3 foot wide/long and that too overhangs 12″. On the day of the installation, we were instructed to “leave them alone so they can concentrate on doing their job”. They did not put the flat steel braces between the underneath side of the granite and the tops of the base cabinets.
You’re the professional that’s installing them. I would be inclined to say not, however, the quality, type and graining of the stone can make a big difference in it’s structural integrity.

The steel support needs to be installed before the countertop. The problem, as you may have guessed, is that the counters are already in place. So this piece of granite is very heavy, very large, and will not move. If all your efforts to have the installers rectify the situation fail, and you decide not to pursue it legally, you can install supports, such as shelving supports.
The what, which, how to and how much – is another topic all together. I just think supporters are a must, no matter what kind of stone you have. They can be sleek or bulky, metal or wood. Corbels can also be spaced such that they are less inclined to interfere with knees/seating, you just have to lay out your seating arrangement and then install the corbels in between the seats.
Trying to retrofit the steel supports that should have been installed before the counter top will be a huge undertaking, and not likely something that the seller or installers will take responsibility for, regardless of whether or not they should have been installed in the first place. Sure, they may pull the top and put in the supports, but if the stone breaks in the process, they will not be held responsible. That’s just the way things work these days, unfortunately. Heavily veined granite will break easier than solid granites such as absolute black. If the stone supplier specified bracing and the installers agreed, then they will have to make it right at their own expense (even if they get breakage on removal). If you have problems with the installer’s work then give them one chance to make things right as per the contract specs.
Contract law is quite specific but varies from state to state. Use exterior glue plywood or cement backer board as the underlay material. Spans should always be kept to a minimum to prevent deflection of the stone. Consideration should be given to the type of stone being used (fragility) and the intended use (load bearing) when assessing support needs.
For all other half-wall overhangs, corbels are required to support the overhang where the bracket depth is 3/4 of the overhang depth. Spacing for corbels is a maximum of 24 inches throughout the span. Particleboard is not an acceptable support material.
