Set of 6. This item replaces the Velcro straps with a plug-in type. The price reflects the limited remaining stock. A set of 12 is also available separately. It is discounted. When using folding cots, it's a hassle to gather the legs with Velcro, and the straps tend to hang down and get dirty during use. This item solves that frustration. With the plug-in type, tidying up becomes easier and looks better. You can leave it attached after the initial installation. Some people tried to force the ring open, so I've included photos of the initial installation method. I saw this at a campsite in America, got the design, and made it myself. I have a Ventlax and a Helinox cot, so I've tested it on those two, but I haven't tested it on other cots. I remember WAQ cots have a similar shape. For other brands, please check the dimensions in the photos at the end before purchasing. Thank you. Helinox VENTLAX WAQ DOD Coleman Tent Camping Gear Helinox Ventlax Coleman
