This is similar to my first Cord Cobra model except this one is specifically for those conventional flat power cords you find on most things around your house. The Cord Cobra Wrapper uses a single piece of 550 cord and two printed pieces. Start with a piece of 550 cord around 2 feet long then cut it down to the length you need once you determine which cord you're going to use it with. The Cord Cobra Wrapper can be easily wrapped around the end of the cord when not in use. This way it stays with the cord and never gets lost.
