Can the hardware be used for a 30" door ?

I am replacing a 30" panel door with a bi-fold door and would like to use this hardware for that purpose.
Asked by: Pramod
Yes, the track is easily cut to length with a hacksaw. I used this kit for my 30 inch door opening.

Customer Reviews

170A Series 36 in. 2-Panel Bi-Fold Door Hardware for 18 in. Panels is rated 4.6 out of 5 by 5.
Rated 5 out of 5 by from Superior hinge kit includes quality hardware I custom built oak panel doors to match others in the original house and needed bifold hardware to match. I was delighted to find that Home Depot carried the Johnson Hardware line and they still manufacture the bifold hardware kit furnished 20 years ago when our house was built. This is a relatively heavy duty kit that easily handles door panels up to 40 pounds with no sagging or binding. All hardware was high quality and nicely finished. Included instructions were clear and easy to follow. I had a 2-panel linen closet door (see photo) installed and adjusted in a couple hours and then completed a 4-panel door that afternoon. The doors open smoothly and quietly and "snap" shut and stay shut. Adjustments allow for correcting for panel warpage so that all panels align perfectly when closed. It was a very satisfying experience to complete this project and the 4-panel bedroom closet door later the same day.

Rated 4 out of 5 by from Replacement of hardware for bi-fold closet door The hardware was installed by a handyman who knew what he was doing.

Rated 5 out of 5 by from Good sturdy kit I installed this kit with wood and glass French doors on my bathroom. Track was easy to cut down to size. I thought the aluminum track looked a little too light but it is holding the doors perfectly well and it opens and closes smoothly. Was pretty easy to install. Had to hang doors twice. I thought I measured where the bottom guide pin went twice but it was in the wrong place the first time. Just needed a helper to hang the door after installing all the hardware. The hardware was easily hidden with some stock trim, since I installed it in existing door jamb. Thinking about buying another for the closet.

Rated 4 out of 5 by from Works well on heavy door I found the quality to be excellent. If you have a heavier door this kit is the way to go. My only issue was getting the door to latch into the top pivot. Not as easy as the video would have you believe. A helper would make it easier. But all in all a good product, I would buy another one.
