We are trying to replace a broken handle on our sliding glass door because the lock is broken. Please see attached the best images I could take.
Here is the info on the door:
PPG Herculite K
Ansi Z-97
1-1972 3/16" U
Tempered Safety Glass
and over to the right hand side it has numbers that are hard to make out. But it looks like either 111372 or 111272
