GFCI in Concrete Wall
My son has a 60's house and on the porch is a non GFCI outlet that I want to convert to GFCI. The outlet box is built into the concrete, is too narrow to fit a GFCI. I know I can change the breaker to a GFCI breaker, but this is the only outlet on that circuit that needs GFCI protection. Question: Is there a box I can attach to the existing narrow outlet box that would extend out from the concrete wall and allow me to install a GFCI?

A picture would be great. A poured concrete wall, around an outlet box? Or, a cement nailed in box on top of a concrete block (CMU)? I have seen a lot of boxes with not enough depth, but can't recall width being an issue on various '50's houses I've dealt with.

They make "extension rings" in various rectangular shapes to fit over the mouth of the box and give more space inside for receptacle units, wires (conductors), etc.
I think there exists although I don't remember seeing one, a "ring" that was slightly larger than a box itself (and with open rear keeping the definition of ring) to fit over the box in the wall.

Depth is not a problem. It is the width of the box. When I went to insert the GFCI, the terminals of the GFCI were too close for comfort. I am talking less than 1/32 clearance on either side. I need something that I can attach to the box that will utilize the (2) 6-32 female threads on the box and extend out. The concrete walls are poured. Not blocks.
Not at my son's house right now so can not post a photo.

Quick redneck fix ...... wrap the GFCI outlet a few times in electrical tape so the contacts are covered.

Something like this:

It's a wiremold extra deep extension box like PC Boss suggested.
They used to make rather tiny boxes back in the day, I've run into those before. Usually it's easiest to cut them out and replace, but obviously in a concrete wall, it's a bit more of a challenge.
