Set of 12 Item to change from Velcro to a plug-in style A set of 6 is also available separately. For folding cots, it's a hassle to secure the legs with Velcro, and the tapes hang down during use, which I think can get dirty. This item solves that frustration. With the plug-in style, tidying up is 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 own a VENTLAX and a Helinox cot, so I've tested it on those two, but not on other cots. I remember WAQ has a similar shape. Please check the shape of the insertion points. Thank you.
