I purchased these to use with the Amazon Basics gullwing drying rack AmazonBasics Gullwing Clothes Drying Rack - White. They work perfectly with this product so I would assume they would also work with similar drying racks.I was originally using the wooden clothespins of yesteryear, though with the tube style drying racks, they just barely fit over the tubes and forget about using them with any thick fabrics. These clips do not have this issue and easily fit over even thick sweatshirts. They work so well, I purchased a second set.I have only used these clips with one load of clothes, however they are very sturdy, having been made from one continuous piece of wire. The coating does not cover the very ends of the wires, though all extend to the tip of the wires, with many extending up to a quarter inch beyond the ends. For my purposes (air drying clothes indoors) I am not concerned about this, though if these will be left outside for some other purposes, perhaps the ends would rust at some point. Something to consider if you will be using them outdoors in all weather conditions (not sure why you'd do that anyway).
