Available in different nickel finishes
The two primary nickel finishes for curtain rods are brushed nickel and satin nickel. The appearance of brushed nickel is brighter than the softer appearance of satin nickel. Brushed Nickel is wire brushed for a smooth finish. Brushed Nickel is a durable finish that is easy to clean. Also, brushed nickel curtain rods tend to be less expensive than satin nickel finished models.
There are different types of headgear
The decorative end of the curtain rod is called the spire. These knobs keep the curtains from sliding off the rod, but they’re also 
part of the overall style because they’re visible to the person in that particular room. Look for the top trim that suits your decorating goals as well as the finish on the curtain rod itself.
There are different types of parentheses
The quality of brushed nickel curtain rod mounting brackets will vary. Anyone who has installed brass curtain rods knows that some manufacturers offer high-quality brackets and hardware. Others leave a lot to be desired. Some brushed nickel curtain rods come without brackets. Regardless, some consumers prefer to purchase individual brackets to ensure the highest quality.
