Chrome tension rod. Really well constructed and sturdy (1" diameter).

Beautiful rod and served us well as a room divider (we put up curtains to divide the room) in our last place, but we just moved and don't need this anymore.

Has rubber ends so as not to damage the wall.

Shortest length: 72"
Longest length: 118"

I remember that this length was quite difficult to find - they usually retail for around $40.

Let me know if you have any other questions.
