does anyone make a 42" bifold?
 

I have a 43" opening at the top of my basement, without room for a regular door to swing. Does anything make a 42" bifold door? I guess I could build a 6" wall stub and use a 36, but I'd rather keep the opening as wide as I can.

It's not visible, so I don't want to spend lots of money on a custom hardwood door or anything like that.

Thanks
