Feszítúrúda

Feszítúrúda, also known as a tension rod or spring rod, is a simple mechanical device used to create adjustable tension between two points. It typically consists of a telescopic tube with a spring mechanism or a screw thread that allows for expansion and contraction. One end of the rod is usually fixed or rests against a surface, while the other end is extended to exert pressure.

These rods find common applications in various household and DIY contexts. They are frequently used to hang curtains in windows or doorways without the need for drilling or permanent fixtures, as the tension created by the rod holds it in place. Similarly, they can be employed as temporary shelving or dividers in closets and cabinets. In some cases, feszítúrúda are utilized in exercise equipment, providing resistance for certain movements. The adjustability of the rod is its key feature, allowing users to customize the length to fit specific spaces and achieve the desired level of tension. Their construction is generally straightforward, often made from metal or plastic components.
