This is the Jingma Coaster-Style Folding Door, a space-saving interior door solution designed for closets, laundry rooms, and pantries. It replaces traditional swinging doors, allowing you to reclaim up to 10 square feet of floor space. You get a full-opening width without the swing radius, which means you can place furniture or storage bins right up to the door frame. I installed this in my own laundry room to maximize shelf space, and the smooth bi-fold action is truly satisfying. Why choose this? It offers a durable steel construction, a clean white finish that matches most trim, and a straightforward installation process that one person can handle in under an hour.
“I replaced a heavy wooden closet door with this Jingma folding unit. The installation was straightforward, and the door glides without sticking. Honestly, the track is a bit sensitive to alignment, so make sure your frame is square. But once it’s set, it works perfectly. I love that I can now access my entire closet without the door blocking the hallway.”

This door fits a finished opening that is 54 inches wide by 80 inches tall. The frame width should be between 53.75 inches and 54.25 inches. Measure your opening before purchase to ensure a proper fit.
Yes. The white enamel finish is paintable. Lightly sand the surface with 220-grit sandpaper, wipe clean, and apply a latex or oil-based primer followed by your chosen color. I painted mine a matte gray to match the room.
Yes. The package includes a single metal handle and a latch. It does not include a privacy lock, as this is designed for closets and utility rooms where locking is unnecessary.
The track is surface-mounted to the top jamb. This makes installation easier and avoids cutting into your door frame. The bottom guide pin slides into a small floor bracket (included).
