Set of 6 Item to change from Velcro to a plug-in type This price is due to the limited quantity. A set of 12 is listed separately. It is discounted. With folding cots, It's a hassle to secure the legs with Velcro, and The tape hangs down when the cot is in use, I think it gets dirty. This item solves that frustration. It becomes a plug-in type, Both the troublesome cleanup and the appearance are improved. Once installed, it can remain attached. Some people forcibly widened the loop to insert it, so The initial installation method is shown in the photos. I saw it at a campsite in America, I was taught the design and created it personally. The cots I own are VENTLAX and Helinox, so I've tested it on those two, but I haven't tested it on other cots. I remember WAQ had the same shape. For other manufacturers, I have included dimensional photos at the end, Please check them before purchasing. Thank you. Helinox VENTLAX WAQ DOD Coleman Tent Camping gear Helinox VENTLAX Coleman
