Double glass sliding door

We won't be able to get you this exact handle but I'm sure we have a substitute that will work well. Before I recommend anything, can you unlock the door, open it a little, and show me the hook this handle uses to lock?

That's a huge help, thanks! Since your door uses a mortise lock, I recommend our 82-032. This is a similar style to your old handle set and should be fully compatible with that internal lock you show me here.
