I ordered this curtain rod in brushed nickel in the 120 - 170 inch wide.  I have a wide patio type glass door so needed a rod to mount 6 - 52 inch wide X 84 inch curtain panels with the grommets at the top.  Wayfair confirmed that each panel weighed 2 lbs and the rod would hold 16 lbs with just the 2 outer supports in the wall so I could pull all the drapes to one side without obstruction.  We in fact did need a center support as the rod sagged in the middle with a total of 12 lbs of curtain panel fabric. The rod is beautiful and quality is great.  We were able to pull 3 panels to each side without obstructing the glass on our encased window but it does cover the wood frame parts of the doors.  The curtains look nice.  FYI, the width of our window door w moldings is 124 inches.
