Installing a Shallow Outlet Box

We have a proposed short wall at a property that they want to make as narrow as possible, but want an outlet also. My question what is the minimum wall depth needed for the 2 inch box in the pic? Can the inner wall space also simply be 2 inches or do we need a little deeper to slide this kind of box in place? Thanks!

That looks like an old work box. If so the depth needed includes the depth of the finish like drywall.

That box is made to work in wall cavity where 2X4's are laid flat with 1/2" drywall. It's a tight fit with the wall cavity only being 1.5" deep.

If it is new wall, use new work box instead.

You can use this box, with 1/2" mud ring.

and

This will give you more room, and fits in 1.5" space.

You can use metal junction box of same style as well.

That side-car box in the picture is an old work box like stated.

It is a pest to install if the wall surface is too thick.

If the wall is open I would go with lambition's suggestion using a new work box instead.

Thanks for all the replies. I think I will go with Lambition's suggestion for the plastic box and mud ring. Also I like AFJES nick name of side-car box. Is that a commonly spoken nick name for the old work box that I pictured? My own nick name for that is sidewinder,.

That is the name I have heard out in the field and some products do even specify the name "Side-Car" such as this item here. There are several different styles of them; new and old work.

The type in your post #1 is good however, it is very difficult to install in an existing wall where the wall covering is thicker (I think up to 1/2" only). Hard to explain but I have come across it a few times in the field. If new sheet rock is being placed ontop of old sheet rock that box more than likely won't fit.
