Hi chris, the bottom section of this door is 9"x21". However, this steel door joint will not line up with any wood door joint so you will not be able to replace a wood section with the steel door sections. Thanks for shopping the Home Depot, the Clopay team

Nicole, the item number is #87700 on HomeDepot.com. Thank you for shopping The Home Depot, The Clopay Team.
Nicole, you may need to purchase a rear track hanger kit that holds the horizontal track to the ceiling if your existing hanger needs to be replaced. Also if you are purchasing the door as a D.I.Y. purchase, you will need to purchase vinyl trim that goes around the perimeter of the opening. Remember, you need 12" of headroom above your opening 10ft. back from the opening for standard track. If you have less you will need to purchase your door with low headroom track.
