The roller type has to have some rattle or there would be too much friction on the wheel (it needs clearance on one side of the wheel). Also, since the doors are only supported on one side (and are very light) that flimsy feel is going to be there, for the most part. Best advice is to make sure everything is level and plumb (including making sure the floor bracket is plumb front to back). It sometimes helps to put a pair of knobs or handles on the door instead of just the one provided. Alternatively, maybe you would prefer a pair of opposing doors, such as separating those bifolds and installing each on it's own set of hinges? It's been done before. Not too difficult if both sides are plumb. If you have drywall on the sides, then first install a jamb set on both sides and top, then install doors (Stanley had some surface mount hinges that will do the trick), then door stops around (or at least at the top), and finally ball catches at the top. No more rattle!

Yes. I chose CDW bc of their warranty, their financing and bc I felt the material would hold up better to the exteme heat where I live. I am not sure I would use them again. We used CDW for 3 sets of bifold doors. We love having them and they really give the indoor/outdoor feeling. However, we had them installed in Aug 2018 and there was an issue at installation that has yet to be resolved. The weather stripping was wrinkled and didn’t lay flat in some places upon installation. The Company agreed to replace the stripping. When they arrived to replace the stripping, it was black not bronze. They said they would reschedule and come back. We later found out the reason the stripping didn’t lay flat was because it was painted bronze and should have been left black. The next time they came, the workman showed up but didn’t have the stripping. The next time they came they didn’t have enough stripping. The next time they came they came with the wrong stripping. I have an appointment scheduled next month and we will see if they can resolve this. Not holding my breath. Luckily I work from home and don’t have to take off work for the appts but it is an inconvenience. Mind you the workman travel 2-3 hours to my home, so their inefficient service department is costing the company money. I note that after the install I noticed one of the glass pieces had a refraction and the Company agreee to replace it no issues. There were a few times that the doors got slightly out of allignment and they came to fix them. I think this is due to the wrinkled stripping preventing the doors from alligning properly. One time this prevented us from locking our door. We explained that this was a safety issue as this was the door to our pool and they repaired it promptly. Overall, I love the doors but their service department is not run effectively. We recently replaced 6 windows in the front of our home. The caulking around the window was terrible and looked like a child did it. (This was not an issue with our doors surprisingly). The frames were scratched in some places. One piece of the window appears to be coming away after a few weeks. The stucco work on the exterior is terrible. The wall texturing on the inside was terrible as well. (We had some construction they did related to the install). I notified their service department. They agreed to let me have my own contractor redo the stucco and reimburse me. They are going to come back and replace the window frames and will recaulk around the frames. Hopefully this won’t take 1.5 years to resolve like my doors. I had hoped to avoid the hastle of a contractor and the pointing of fingers when something goes wrong, but their construction work is sub par. I am annoyed by the inconvenience of all this as I just wanted to check these projects off my list but can’t.

Mark, funny comment. after a lot of searching, I found what I thought was a good pick for bi-fold doors. (for my laundry closet. no room for reg. doors) Home Depot had solid oak bi-fold doors. Apparently they are out of stock. right now I've got those hollow louvered doors and they are crap. thinking I may have to have someone make something because I can't find any suitable replacements.

Beth it isn't a matter of the finish - it's a matter of them 1) being hallow so feeling super cheap 2) the panels and mullions colonial/traditional look, when the rest of house has a MCM aesthetic including the original, flush interior doors and 3) the cheap bifold hardware where about half them have popped out of the track. The Johnson hardware system looks SUPER heavy duty. If I could just get the panels made to order somewhere, I think I could handle getting the hardware added myself. I'm pretty crafty at this point. So at this point it's not so much a matter of buying "doors" per se, I just need a manufacturer who will 1) cut a piece of MDF to your size spec and 2) veneer it to your spec It's interesting how flush doors are harder to find than solid ones...and while there are plenty of solid panel doors out there, there are not many solid flush doors. Solid flush doors are probably way more common in commercial buildings, where they are often just steel of course.
