You need a deadbolt and a knob or lever. Am I misunderstanding the question?

Yes, trying to avoid the dead bolt.

i have seen knobs and handles with ver long plates. I see then for sale, but can’t find get an idea how appealing it looks.

I want to apply for this too. Can I learn the details of how to do it?

Why do you have this to begin with maybe a bit more info or a new door.

It might be cheaper and easier all around to buy a new interior door and fill in the hole on the frame with wood filler. Is there anything particularly special about the interior door?

Look for a pair of push plates to cover the door stile and drill a single bore hole in it or just through the deadbolt in and do not use it.

Or just use a blank door plate.

I i have these free mahogany doors with two bores for interior. Mistake and hence why I have them free.

Trying to use them for my home.

worth keeping?

Could one bore be filled successfully?

stain vs paint? Thank you

Seems you wouldn't want to paint mahogany doors otherwise, why have mahogany? I think @GN Builders L.L.C suggestion is good and then you could fill the side of the door and stain it to blend.

Or something like this, hung upside down (assuming the deadbolt is on the top), although the above suggestion is less noticeable. The below makes a statement that might not blend with the other doors in the house. But you may have enough doors to do them all this way and it might look interesting.

A skilled person might be able to fill the bore hole but you might have to restain the whole door to match.

After all this, will it match your style?

Reminds me why I should never take in another "free" cat. :-) I do appreciate you are trying to keep them out of the landfill.

Thank you.

They are not stained yet, so I can pick any color.

appreciate all the suggestions. Will post A pick when done
