Widest opening would be a five foot French door, either inswing or outswing.

Thanks. I was hoping to find a slider where the fixed panel could be removed but most of them seem to be manufactured differently these days.

The door isn’t protected from the elements at all at that location so I hesitate to put a french door there. But there’s just no choice I think.

Can anyone recommend a brand available in the Midwest (IA) that has a five foot french door white/white standard?

Every brand has white as a stock color. Go to a couple showrooms and look around. Outseing doors tend to seal better than inswing if that matters.

Thanks I didn’t know that

A sliding door is always the problem that it does not even open half of the entire width. French doors and Patio doors are your option. Either you have a wide door panel at max 42 inches with a fixed side lite or you go with a double door system that is either split in the middle or off center. Your least expensive option is 42 inch door with fixed side lite. The side lite can be just a piece of glass that is framed next to the door. Best of luck.
