support needed for 12' granite overhang?

15 years ago

I have a 3x7 island, 1' of which will be an overhang.

Will I need brackets or some type of support for the overhang? My KD says no, but everywhere I see similar set-ups, there are brackets supporting the overhanging countertop.

Hi mmme. I have a 57" x 68" island with a 12" overhang. Granite templates were made on Friday and they will be putting 3- 20" long steel plates into the underside of the granite for reinforcement. Here is a pic of the template they made. They said they always reinforce any overhang more than 11".

Yes, you do need to support it. You can search on this forum for lots of info on that subject.

My island at my last house was 66" x 38", 13" of that was overhang. I did not have brakets or corbels supporting it, and was told I wouldn't need them. We never had a problem, despite lots of kids and heavy entertaining. Our granite as standard 1 1/4" stuff.

Standard recommended support for an overhang on 1.25" material is 8", with a corbel or support every 30" of unsupported overhang.

I was told I needed supports, and I was told I didn't need supports. I have 11.5 inch overhang. I opted to go without corbels/supports. I hate them. IF we do NOT stand or sit on it, I was told I'd be fine even by the guy who suggested the corbels. I hate kneeknockers!

You do not need "knee knockers" to have adequate support. Ask your fabricator to enquire with a company called "Chemical Concepts" for their "Counter Balance" support systems. (See link)

They offer support without being obtrusive.

I hate knee knockers and corbels too but I wanted some support for a 12 inch overhang. I opted for steel L brackets that you can't see. I got them from the internet - website and their pics of installation like mine is attached. The guy I spoke with was very helpful as well - definitely knew his stuff.
