I just read the posts dealing with the sealing of a metal frame and they made me want to ask this question ---- I use the method of filling the gap in with extra foamcore and matboard. Usually using a piece of black matboard as the last piece --- to make it look nice. The problem with doing this is the fact that I do not have much room to run the wire through my eurohangers. So, should I apply the wire before filling in with foamcore and matboard, or is there something out there other than eurohangers for metal frames? Thoughts appreciated.
