Calhome bi-fold barn door with sliding hardware kit contains everything needed to transform any doorway from a traditional door into a convenient, space-saving, and stylish sliding bi-fold door. Bifold doors are folding doors made up of two pieces of door leaves that can be folded when opened, maximizing the use of space. Compared to sliding doors and swing doors, bi-fold doors can open up a wider space while saving 50% of floor space (swing space), making them ideal for installation in areas with limited space, such as bedrooms, bathrooms, kitchens, and more. Calhome Finish: Black, Size: 30" x 84"
