Thanks for posting. For the sliding glass door, I am not precisely what you mean by the latch. The mortise lock resembles our 82-227; this lock works with keepers like our 89-020, 89-021, or 89-021D. If you mean the thumb latch within the handle, consider our 82-106. If you need a different item, please specify and send pictures, and I'll try and find something better. For the screen door, the handle set looks like our 83-126, which can work with keepers like our 85-011 or 85-014. See the diagrams below and let me know if you think one of these keepers could work for you. Dimensions for 85-011
DImensions for 85-014
