Sliding glass door latch set

Thanks for writing in. The handle set looks like our 82-086, while the mortise lock is the 82-265. For a new keeper, see the 82-249. Please compare these parts to your old hardware and let me know what you think. 

Yes, the 82-086 handle set has an exterior handle. If you haven't already, you should visit the store page I linked you to in my previous response. This page has detailed photos and information that you can use as a reference to make an informed purchase.
