ZOPZO Curtain Rod Adjustable Window Drapery Rod, Black, 48-84 Inch, Heavy Duty Curtain Pole for Living Room Bedroom Easy Install

I had my doubts but, for the price... This heavy duty curtain rod comes with assembly instructions and all necessary hardware including a center support bracket. A phillips head screwdriver (not included), is the only tool you'll need to install this curtain rod. This rod is fully adjustable to ensure a great fit even with odd width windows. The rod comes in several sections that fit tightly together giving good structural integrity. The two and portions also have twist adjustable mechanisms that retract and expand to ensure an exact fit. The rod screws into the brackets for a most secure assembly. As far as the installation went, it was very easy. I was able to assemble and install with curtains in less than 10 minutes by myself. All you have to do is mount the end and center brackets, place curtains on the rod and screw into the mounted curved end brackets. The center support bracket also has a screw to tighten the curtain rod down to prevent the rod from movement when opening and closing the curtains. I used them to hang five heavy woven 52"x120" grommet top panels over a sliding glass door. Even with frequent opening and closing of the curtains I have not seen any bowing in the rod. The hearware has remained secure and stable. Finally, the curtains slide freely and don't get hung up when opening or closing.

love the curve, completely blocks out sunlight with black-out curtains
