What is the most overhang you can have on a Kitchen bar with no supports on a 2×4 wall with 1/2″ drywall and 1″ overhang on inside? With 3cm material bar is L shaped 90″ X 57″.

Dirk,

Welcome to the FabNet.

Official rule is: 1/2″ material = no more than a six inch unsupported overhang. This could easily be extended with steel or ply recessed in as substrate or build up. If we were talking about a peninsula or island on cabinets, you could push it to twelve – more with the steel we use.

The cantilever rule is in play, however: two-thirds support for one-third free overhang, but you can squeeze a bit more if you first fasten your solid medite (MDF board) or ply build up direct to the wall, then fasten the top to that.

Your question is somewhat lacking in detail, but this should keep you safe, anyway.

Is there a particular situation you’re worried about?

Dirk:

DuPont’s Zodiaq 3cm quartz surfacing remains under warranty with a fourteen inch unsupported cantilever.

I’m not saying that’s what I’d recommend for a 2×4 wall, however.

How do you plan on attaching it to the wall? If there is nothing supporting the 3cm material, when you lean on it, what is going to happen?

[Dirk Williams]

What I have is a 13″ bar top sitting on a standard 2×4 Halfwall attached with silicone on the kitcken side I have a 1″ overhang on the other side somewhere around a 6″ overhang with 3cm EOS. What I was wondering was at what point do you need supports under the overhang 6,7,8,9….”. Like with Andy”s question when someone leans on it.

Thanks for all the advice

Dirk,

Under the circumstances you describe, I would definitely go with some kind of bracket support.

As for any other general overhangs, as long as it falls within the max allowed limits, I would follow the two-thirds rule.

EOS allows 12″ unsupported overhangs, I’m a little sketchy on the details you gave but it sounds like you are going to need some support just to keep it from teetering on the wall.

Dirk….. Order you several corbels to support an application like that. About any bar overhang, not only will you convince the homeowner it needs it, but you will pick up and extra $100 for every 4 you install. Send me an email, I’ll send you my source. they are are just an ups delivery away…

Got it.

There are brackets that have no angle support. Sure, they give up some strength, but they are pretty strong anyway. You really don’t need much, do you? Just a bit more than is wise without support.

If you have access to the stud, fasten them between the stud and the sheetrock. If not, face mount it and carve some caps out of the material for cover later. Recess route the top rail into the material. I doubt you’d influence it at all in the negative, but Gordon is the official EOS go-to guy.

This is going to cost a little, but it essentially satisfies the criterion of the homeowner, while leaving little more than a decorative doo dad. It should cost something, and you should profit from it.

My thoughts on this are, go with KC and make it look nice while adding alittle to your pocket (with minimal extra work). Or go with Tom, figure out a way to get the brackets under the sheetrock ( with alot of work) and make it look like it floats (charge alot more).

At the very least, if I understand the description right, the limit of the countertop is not the question as much as the limit of the connection to the wall. Whatever you do, if there is even a small tiny doubt in your head, don’t leave it hangin with no support. You will never be able to get any sleep.

‘Cause I don’t know about you, but the idea of 15 per square greeting my bare feet in the morning is, well, undesired.

If it’s gonna look like it’s special, and work well at the same time, it shouldn’t be cheap.

You can’t just give away your liability, what would tort lawyers live on?

[Andy Graves]

I wouldn’t go more than 3″ without some sort of bracket or corbel. As soon as someone lean on it the thing will start coming loose from such a small surface area to silicone.
