Thanks for the suggestions. . . Hm. Did I word it wrong or something?

Hi Sdionnemoore,

Do you need them for support? Or just for looks?
I ended up with 1/2 round fluted columns in my kitchen
because I wanted the "look", I don't need the support.

I wish I knew how to measure for them. : (

You can buy them at Lowes or HD but they will be really
pricey. Well I am shopper for deals I found molding
products at these different places. It takes a week
or so to go through the mail but worth it. Proabably
similar to Ebay. I would send a question to the Ebay
seller or check out the links of catalogs below. Maybe
they have details.

I included a GW link maybe this can explain better too.

Here is a link that might be useful: Support for overhang on granite counter top.

I am using the steel reinforcement plates under my granite overhang instead of the corbels. My overhang is 15" on a island a little over 7'.

Sorry I can't be of help, but didn't want to leave you hanging. I am not sure how many people have the corbels as overhang support here - that's perhaps why you aren't getting many responses.

We have a 10' island with about 6 1/2' of cantilever for bar stools. There is cabinetry on either end of the cantilever.

We had metal rods fabricated to support the granite. No corbels. The depth of the overhang is about 13''.

Thank you all so much. Boxerpups, your links were especially helpful.
