The 4 foot bar come in 3 pieces.

These sliding doors are so nice! The move smoothly, look really nice and we love them. I do recommend painting before installing and then touching up.

Exactly the item I wanted, sturdy
I've been trying to find a hardware kit for the doors of my closet, but the regular kits require too much space and I don't have too much room to install them, I found this 3.3ft bi folding barn door kit and it was a perfect choice, he managed to set it on my closet very beautifully, this kit is slightly more expensive compared to the regular kits on the market, but when I received the finished product found that he is definitely worth it, its pulleys slide over the rails very quiet and smooth, feel very good, the quality of use is very strong, so far there are no problems, it is my first choice.
I checked some reviews before I bought it and they said the installation process might be a bit bad, but when I received the item and installed it, I would say there are indeed a lot of parts, but don't think it's too complicated, try to carefully check this manual or ask their technicians, it's all very easily solved, I installed these kits by myself with my family and also asked Their technicians, they also provided me with an orderly installation manual, I got good communication there, it was a rare experience, by the way, some wood chipping parts that need to be embedded in the wall, please be sure to pay attention to the installation instructions when installing, some care is needed here. anyway, everything is very good.

I have not installed these yet. When we do months from now, I'll add a photo and any updates to my review. We've put up many a barn door but this will be our first bifold barn door and we're putting 2 sets together for a wall of doors. The rotating hangers seem to function like they're supposed to. The track etc looks the same as others we've bought in the past except it has considerably more splices instead of long pieces of track. ( a 10' we bought before was just 2 pieces of metal and a connector for the center) This company didn't offer a connector which I plan to hide the cut on of 2) 5' sections for my 9' opening which will have custom doors made for it. They completely stood behind the products I ordered and provided me with the correct size splices for 9' track so I don't need a connector. Not many companies today go above and beyond like that. I read other reviews about the wall plugs. Even though these tracks came with those we don't use them. Instead, we put up a header of solid wood because the spacing of the holes in the track never hit on the studs and this not only looks good but gives it more strength.

We own a boutique hotel in Puerto Vallarta and have a ground floor suite that we needed to make more user friendly for guests with mobility/wheelchair needs for access to the private bathroom. All of our walls are solid concrete and not exactly square. After we bashed out part of the wall, we installed the hardware. It took a bit of adjusting but the hardware itself is sturdy, and the instruction were fairly easy to follow. If someone was not great at DIY, it could be a bit tricky. Very pleased with how smooth the doors roll, and the look is exactly what we wanted. I may order the straight hardware next and do a barn door in one of our other suites.
