locking larch for NAMI 51168 Opera Patio Door

Hey there,

Thanks for reaching out to us! This handle set reminds me of the 82-078 Sliding Door Handle Set. I'm afraid we do not have a replacement match for it compatible mortise lock or the keeper used with it. Unfortunately, we cannot be sure that they are available any longer.

Our sincerest apologies that we could not be of more help with this repair but please don't hesitate to reach out with any additional questions you might have!
