The TrueLiving Window Curtain Tension Rod is adjustable from 48-84" to accommodate your window. With non-slip, non-scratch end caps help protect your window frame and walls from damage. The tension-mount rods stay securely in place between two walls, a window frame or doorway to hang shower curtains or drapery without drilling holes. After choosing the adjustable size that best fits your space, expand the rod to achieve the right amount of tension for a secure fit. Installing only requires a few simple operations, no complex tools are required, and it is not easy to cause damage.
