This J Top Mount Heavy Duty Bifold Hardware Kit is compatible with doors from 1-3/8 inches to 2-1/4 inches thick.

Yes. A header board distributes the door system's weight evenly across the wall to prevent drywall damage and allows flexible track placement without being limited to wall stud locations.

Use hardwood that can support your door's weight. Good options include:

  • Red Oak – Strong, durable, attractive grain
  • White Oak – Strong with a lighter color
  • Maple – Excellent strength, clean appearance
  • Birch – Solid, affordable, readily available
  • Poplar – Consistent and easy to paint

Avoid softwoods like pine, which may not support the door's weight over time.

Minimum 1" thick and 6" wide. Length should extend to the next wall stud beyond each end of the track to ensure full support.

For this Goldberg Brothers Heavy Duty Bifold kit, the track dimensions are:

The standard kit supports up to 500 lbs total and is ideal for hollow-core doors or lightweight solid wood panels up to 24"W × 84"H each. The heavy-duty version supports significantly more weight for larger, heavier solid wood doors. If your doors exceed 500 lbs combined, choose the heavy-duty option.
