These did not hold anything. Despite following directions exactly as written, my curtains came crashing down within minutes doing some damage to my floors. As a consumer of 3M products for years, I wouldn't stand by these hooks if I were being paid millions. Sadly, I am now out a lot of money having ordered online and paying extra for expedited shipment. I will be drilling holes into the walls going forward and will warn all I can to not waste their time or money on this product. It should be discontinued immediately.
