I had never installed bi-folds doors until I renovated my basement. The doors I bought (special order solid-core doors from Menards) are outstanding, however the included hardware left a lot to be desired. The included Johnson hardware, requires you to pick up the door and try to hang it from the track. My take is that for hollow core doors this is probably not a big deal. But for my 40-80 pound doors it is a bit on the tricky scary side. And since the operation requires getting fingers in small closing places, outright painful if you pinch or crush one of your digits.
For a bedroom, I had a dual pair, and the kit came with two 2' tracks, which is cheap looking. So I went out looking for a replacement track. At Home Depot I found Stanley's Bi-fold Hardware Set, which I know now is EXCELLENT.
Here's a list of what I like:
- The track is shorter by over a quarter inch reducing the gap between the door and the opening
- The height of the door is adjustable by turning the bottom pivot's screw mechanism.
- Installation of the pivots simply requires drilling 3 7/16" holes.
- To install in the track, simply insert the bottom pivot, into its grove. The top pivot and guides are spring loaded so simply dress and release.
- The glide on these things must be felt to be believed.
In other words, no scary getting your fingers under a heavy door that could fall on your fingers. And no cirque-de-solei acrobatics to try to get the pivots into their receptors. If I ever finish my basement and find myself idle, I might replace other hardware in the house with this stuff.
