A tension rod is a versatile tool commonly used for hanging curtains or creating space dividers. It consists of a long, adjustable rod that can be extended to fit snugly between two surfaces, such as walls or inside a closet. The rod relies on tension to stay in place, making it easy to install without the need for screws or brackets. These rods are often made from materials like metal or plastic and come in various sizes and styles. They are popular in homes and offices for organizing spaces, as they can hold lightweight items like curtains or clothes. Tension rods are also used in shower curtains and window treatments.
