iDesign 1.8" Adjustable Shower Curtain Tension Rod, Black

A little background on this rod: the instructions state to pull this rod to ONE inch larger than the opening you need to cover. You then TWIST THE ROD TO LOCK it in place (you twist until you can't turn it any more). With most tension rods you have to keep twisting and twisting just to get the length you need and it's usually several inches beyond the size of the opening. When they say an inch for this rod, they actually mean an inch. You can actually measure it to the length you need, lock it in place, and the spring inside allows you enough room to fit it in the space you want it without scuffing and scratching everything in its path...and it stays in place! I'm actually using these in my living room windows to put thick curtains behind the decorative ones to help keep heat in. Works like a charm just as expected. Holds in place well and I just love the look of the black finish. I think it is a very classy look in a shower since you always see stainless. the finish is very attractive with my decor. Very impressed with this product

I really like this rod. The only issue I have is that it only extends 42" long. It's not long enough for a standard tub/shower combo. I had the bright idea that I would use it for my master bath shower. However, I did not take into consideration that the shower is a corner unit. There are no sides that have 2 walls. I will find a use for it!
