A double-acting door, also known as a bi-directional or impact door, is a type of door that swings open in both directions, allowing entry and exit from either side without the need to pull or push the door back and forth. This design is often used in high-traffic areas, such as restaurants, hospitals, or commercial spaces, where ease of access is essential. Double-acting doors may be made from various materials, including glass, wood, or metal, and can include features such as spring hinges to help them automatically close. They provide convenience and efficiency while enhancing the flow of movement between different spaces.
