PPG HERCULITE Patio Door Handle

I'd be happy to help you find the lock assembly you need, but unfortunately that code you gave isn't relevant to the door. That only tells me who made the glass, which is a different company.

The best way to start with this kind of project is to submit photos of the old handle and lockset here for me to review. I can then check our inventory for a potential match. Please let me know if that's possible and we can work from there.
