Even though this bifold is advertised as 36" x 80" please be aware that it is NOT in fact that exact measurement. It's meant to FIT in a 36" frame, which means that both sides have a 3/4" gap and the bottom has a 1.25" gap. That's pretty significant if your purpose isn't to use them as closet doors. And even so, you may not appreciate the giant visible gaps around the entire door. Buyer beware!
