On closer inspection:
The tempered glass fits into a "u" shaped vinyl glazing strip that has rib
on each side. The glass and glazing then fit into the "u" shaped metal
channel which forms the piano hinge. I can see that the interior of the "u"
shaped metal channel also has ribs. The metal ribs must lock the vinyl
ribs. This seems like a clever way to get a very tight fit. Maybe intended
to be irreversible? Razor blade is defeated so far. Ideas?

I would like to reverse the hinge on a pivoting shower door. [The glass is
textured on one side and I'd like to keep that on the outside. This
requires that I move the hinge and not just flip the door.] The door is an
unframed panel of tempered glass with one side inserted into a metal
channel with the pivots. The glass is held tight with thin rubber strips.
In past experience the glass worked out of the rubber strips easily. This
one, although the rubber is fresh and pliable, is stuck tight. I ran a
razor plade under the rubber as far as I could. Gentle tapping with a
rubber mallet did not work.
Any suggestions to avoid breaking the glass?
Thanks.
