If the cross brace is horizontal (and not vertical as you drew it), then I don’t see your problem. The cross brace should not interfere with the D rings or hanging wire in that orientation. Can you restate the original problem please?

Sorry, but I do not see your problem. Why would the brace interfere with your hanging wire in the slightest degree? Even if the apex of the loop of your hanging wire were directly behind the brace, what possible interference would that have upon the hanging of the painting?

it seems to me if you wanted it as flat as possible against the wall – as I think the bongolian had stressed – then the brace and the picture hanger(s) have to be in different locations. The hanger(s) and wire can be below the canvas level by being in the recess behind the canvas except where the cross brace is.

Unless the brace is of a greater thickness and somewhat raised above the back of your frame it would be the same as having a solid back frame. A framing wire hanger should work fine.:)

This is the way that is suggested. If your brace is level with the back of your frame this should work perfectly.

Marc, is right and my post was a complete mistake in not understanding the problem. I used to have a router bit called a Keyhole Slot Router Bit that I have used in the past. You plunge the bit into the back of the picture frame and run it down a length of the frame creating a channel for the head of a nail or screw. You can adjust the depth of the channel desired on the router. The point of the plunge creates a hole in which to insert a nail or screw head that had previously been fastened to a wall. I have a few frames hanging with this system hanging in my home. There are several places such as Rockler Wood Working that sell this type of router bit. I hope this helps.:)
