What size opening does this door fit?

It is built for a 48-inch-wide opening: a 36-inch door plus a 12-inch sidelight, at 112 inches tall. Check your rough opening against those figures before ordering, since it is taller than a standard door.

Does it come prehung with the frame?

Yes. It is sold as a prehung unit, meaning the door is already mounted in its frame with the sidelight, ready to set into the opening.

Which way does it swing?

It is a left-hand door, so it hinges on the left as you face it from outside. Confirm the swing direction against your entry before buying.

Will a steel door rust?
