Your mortise lock is very similar in design to our 82-239. This may be what you want, but please understand that we cannot garner precise size from a photo of a ruler. You'll need to review our listed dimensions to verify that they all align.

Ok thank you. What is teh difference between 82-239 and 82-259? Finish?

The 82-259 is made of stainless steel, which is handy if you're in a salt air environment.

so the 82-259 is the exact same at the 82-239, just in stainless? So the 82-249 keeper will work for both of these latches? Lowe's installed this door in the home before I purchased, and it has been very hard to find a replacement latch and keeper.

Yes, the 82-239 and 82-259 are identical aside from material and are compatible with all the same parts.

Just make sure that you review all listed dimensions before you buy anything. Size is the final determining factor.

Do you know if my existing handle for the reliabilt 332 will work with this latch? Or do I need a new one of those as well?

I don't know what handle that particular model door used, but looking at your first batch of photos it appears to be a typical design. I don't see anything that would raise any concerns, but if you do please let me know and I will do my best to address them.
