needs a handle for the sliding door

Hi there!

Thank you for reaching out us. We might be able to help with this. Can you write out the distance between the two installation holes, measured from center to center?

We can't be certain since it's hard to get an accurate measurement from photos of a tape measure, but it looks like the installation hole center spacing may be 3-15/16". You'll want to confirm. If that's the case, take a look at the 82-030. We can't promise this will be compatible with your old mortise lock, but it'd be the best we can offer. Review the specifications and see what you think.
