Which type of door slides into the wall when opened?

1. Pocket door

2. Sliding door

3. Bi-fold door

4. Bi-pass door

The correct answer is: Pocket door

A pocket door is designed to slide into a wall cavity when opened, effectively disappearing from view and maximizing space in a room. This type of door is particularly useful in areas where swinging doors would take up valuable floor space, such as smaller rooms or hallways. The mechanism allows for a smooth operation, typically using a track system, and the door remains concealed when fully opened, providing a clean and unobstructed passage. The other types of doors listed function differently. A sliding door moves along a track but does not slide into the wall; instead, it stays exterior to the wall. Bi-fold doors consist of multiple panels that fold against each other to open, requiring space alongside the wall rather than recessing into it. Bi-pass doors also slide on a track, allowing two or more doors to pass by each other but, like sliding doors, do not disappear into the wall.
