Matched my previous hardware but with greatly improved rollers & pivot points
8-2024: Installed a longer 6′ version in another location & the install went 2X as fast ’cause I knew exactly where I wanted everything to line-up. This time I installed new oak panel doors & had to cut their bottoms to match a pre-existing door frame. I made my cuts exact & everything lined-up & works perfectly.7-2024: The previous owners of our house chose only top-quality components, which is why we bought the house, so I wasn’t surprised when this high-quality bi-fold door hardware arrived and the hinges were nearly exactly the same except for the color. Therefore I could use the same holes as before for the hinges, which was a timesaver. However, this new product has much improved top rollers and lower pivot points, which was the weakness of the previous design. Our house has Amish-built solid-oak doors throughout, so IMO the weight of or bi-fold doors, over a 20+ year period, wore-out the bearings on our previous rollers. The new rollers & pivot points are a much sturdier design, so I expect them to last a long time.Regarding installation, the instructions are vague but because it nearly matched the previous hardware, I could figure-out everything by taking pictures before I took-apart the old hardware. A key help is that you need to push-up the top pin all the way up into the wide hole, drop the bottom pin part-way in, slide the top pin inward to the smaller slot, let it drop down / settle into the smaller slot, and then push-in the plastic flange. The plastic flange pushes outward and appears to cover the top of the pin so that it cannot pop-out and move over to the large removal hole. Another help is that the top and bottom pivot point can be adjusted after installation which helps you to dial-in the best location / smooth action. Once done I placed some white grease on the top track & both sides roll smoothly & stay closed once shut. Very nice kit & highly recommended!

Upgrade to typical bifold door hardware
Builder grade bifold door hardware is terrible and wears quickly. This is a definite improvement. Install was easy. Had to patch deep 3/8” diameter holes in existing doors from old hardware and this was the difficult part. New doors would have been easier. My only complaint and not a big deal….the hardware is all quality and solid then they include some cheap plastic handles. Why even bother! Just kept to old wooden ones

The rails and hangers work, the rest is junk
First, it come with no instructions. The rail and hangers work and look like they are decent quality, the rest is junk. The screws break easily. You need to predrill bc the screws can’t handle even particle board. Highly recommend buying the hardware at hardware store to put it together.

Be ready to modify
Whoever designed this deserves a strongly worded letter (to say the least). To start, the hinges are the most annoying thing. Trying to mount doors with open hinges like this is insanely frustrating. Second and maybe even more frustrating is that the floor mounting hardware also brought me close to throwing the whole project out the window. I ended up breaking two of their cheap garbage screws trying to secure the hardware to the floor, even with pilot holes ready to go. I also ended up scratching up the front of the doors and side jamb trying to secure this piece to the ground after the doors are hung. This is insane. I do this for a living and will never recommend this product to anyone doing anything custom.
