I did three searches on this, came up empty handed...

When I use my Anti-Newton glass neg carrier for 4x5, it crops into quite a bit past the frame edge, slightly less using the Negaflat carrier, on a Beseler 45MXT.

Other than buying another glass carrier, filing it out and getting Focal Point to make some custom glass, what are my options for getting closer to if not all the neg represented in when printing from 4x5 negs?
