This extendable tension rod is crafted from high carbon steel with a fine finish, ensuring durability and sturdiness. Designed for easy installation without tools, it fits snugly between two walls using internal spring tension for a secure hold. The rod adjusts from approximately 12 to 19 inches (30 to 50 cm) in length, with a diameter of about 1.3 cm (0.51 inches). It is suitable for use as a shower curtain rod, bathroom towel rail, or wardrobe rod, but should not be used to hang heavy items like clothes to prevent damage. The rod features anti-slip rubber ends that increase friction and help maintain a tight fit. To install, rotate the rod to the desired length, ensuring it is slightly longer than the space between walls, then press into place until parallel with the floor. The product weighs approximately 66 grams and includes one tension rod. Manual measurement may result in slight size variations.
