I have a closet 2.10 metre high in a corridor. It is divided into a lower part 145 high, and an upper part 65 cm high. Each part has 2 shutters . I would like to replace the 4 shutters with 2 long ones . Is this possible to do that while keeping the interior of the closet as it is ?

May be easier to attach a small thin panel that connects the 2 together. Now you have 2 shutters.

I don't think this is possible because there is a thin horizontal panel separating the lower and upper part. Tks anyway for your suggestion

Then get a larger shutter and surface mount it. The shutter will be a little bit larger and overlay the frame. Why not just keep the original setup?

Thanks, I will ask the carpenter to do that. I was asking about the possibility because redoing the closet needs a larger budget.
