Like the last poster said make sure the opening is the proper width to fit a pre hung unit. Like he said prehung units that big are a lot easier to move with the doors removed. Mdf Doors wiegh a ton and 2 of them in the frame would be impossible to move. A frame can be jockeyed around a tight stairwell. There is another route if the openings are a non standard size, bypass doors. All the closets in the bedrooms have them and I just ordered door blanks and installed them on new hardware. I recomend Johnson hardware for bypass doors. It's cheaper to order from the company than have a big box order it in. Here is a link that might be useful: johnson hardware

I replaced the bi-fold closet doors in my bedroom (for my linen closet) with curtains (drapes) that I made from silk damask fabric that I happened to have in my sewing room, not being used. I also lined the drapes with silk - I get a lot of free fabric at work. I did not like the bi-fold doors for several reasons - one being the look, and another being that they would get stuck on my carpet. The damask that I used is a bit stiff, but it still works. I call them drapes because they are lined, but I hung them on a tension rod like curtains. How big is your opening? Mine is very narrow, since it is just a linen closet.

kudzu, there are no jambs. The pivot base is screwed right into the top and bottom of the door opening on the problem door; thus into the wood under the drywall at the top, and into the wood floor at the bottom. I just went and checked it. The base is secure top and bottom. It's the metal pivot going into the door that is wobbling. The door starts tilting at the top, where it starts hitting the side of the door opening at the top. When the people installing the doors installed them, I guess they didn't know that a solid door needed more. I ordered the doors custom made so I could stain them to match my kitchen, and they did say they'd never seen anything like them. Last time he replaced them, my husband just went to Menard's and bought them, so I don't know if they were labeled for load capacity. Said if these failed, we were out of options. That's got to be it. Thank you so much for telling me about this! These are just too flimsy for the load of the solid wood oak door we bought. The door is tilting again. What kind of load capacity should I be looking for? Should I just weigh the door when we take it off? Can you get a variety of ones with different loads at a common home improvement store, or is this something I will need to order?

Hi, I don't think bifold doors is a great plan as you lose a lot of width in the doorway when they are folded against the wall. If you're coming in with groceries, you are going to have trouble getting through with your hands full into a 30" wide space that has at least 4-6 inches of bifold door folded. We have a similar issue at our basement stairs and we have two narrower "french doors" that latch in the middle. Here is an example. Depending on the hinges you use, you may be able to get them to fold back more than 90 degrees which would help with your traffic flow into the kitchen. Have a look at Richelieu Hardware for hinge options and other clever ideas.
