Mortise lock backset not deep enough

I'm afraid your photos didn't come in. Could you try uploading them again? Make sure to check the size of the file. Some cameras save photos in extraordinarily large file sizes, which can strain our system. If you reduce their size a little that should allow them to upload. Thank you!

Thank you! I think you may have wanted our 82-229 instead. The depth appears to be the same, though it's hard to tell from your first photo if the installation plate extends further like on ours. To put it simply, the installation holes for the 82-244 are inside the "cup," while the installation holes on the 82-229 extend outside the "cup" on tabs. Does that make sense? Look over our 82-229 and see if this would make a better replacement option.
