Tension rods are adjustable rods used to create tension between two surfaces, often for hanging curtains or other lightweight items. They work by being compressed between two walls or surfaces, allowing them to stay in place without the need for screws or nails. This makes them a popular choice for renters or those who want a temporary solution. These rods come in various sizes and materials, such as metal or plastic, and can be easily installed and removed. Tension rods are versatile and can also be used for organizing items in closets or as a support for shower curtains.
