patio door

Hello there. The Legance 3 brand is generally associated with our 82-080 Handle Set. However, the distance between the screw holes that mount this handle set to the door are 4-15/16" apart. Handle sets that have this distance at 3-15/16", such as our 82-030, work with entirely different locking mechanisms. To be safe, it might be best to send me a picture of your door's mortise lock. That will confirm it either way. 

These photos are a huge help, thank you. Seeing the way it installs, I think our 82-080 is definitely going to be our best option. There are just a few concerns.

1. We don't have a version of this handle set with a 3-15/16" hole spacing. These are only made in 4-15/16" as a rule. I suggest triple checking that just to be 100% sure.
2. I'm concerned at this stage that the thumb lever that comes with the 82-080 wouldn't be compatible with the existing mortise. Note that the "stem" on our thumb lever is square shaped; I'll share a reference photo below.

My hope is that even if your holes are 3-15/16", you could need to drill new holes and just mount our handle using those. Theoretically that would still work, but only if the existing mortise lock can take the same square "stem" off the thumb lever. Look it over and see what you think.

Thanks for getting back to us. The 82-080 would be our best replacement option based on your photos and your thumb latch does appear to have the same shape and orientation as ours. As long as the dimensions below match, I see no obvious reason why it wouldn't work with your mortise lock. With that being said, you would need to make new installation holes in the door to accommodate the 4-15/16" hole spacing of the 82-080. If you decide to go that route, you'll need to be very careful not to hit the glass in the door. If you run into any problems, our return policy can be found here. Take a look and see what you think.
