The Home Entertainment Cord Identifier Kit from Dotz allows you to identify and match cords for cord management. It makes the most complicated home theater, gaming or TV/phone/internet installations easy.The kit allows you to match colors, numbers and text on both ends of the cord to easily identify your electronic device connections. The kit is ideal for receivers, monitors, TVs, Blu-ray players, cable boxes, stereo/speaker systems, gaming consoles, networks and coaxial cables. It can be used with cables for wiring behind walls, on separate floors or in different rooms. You can choose one of the two cord identifier sizes to fit around a full large range of cord and cable diameters. You simply need to punch out one of the inserts (12 colored and numbered combinations to choose from), write the device name or location on it and snap it around the cord end. Repeat the same process for the other end of the cord. Put a matching sticker to the device's input or output and plug in the cord. For future reference and convenience, you can record your identification method with a corresponding sticker on the device chart that comes with this kit. This makes changing out a device or adding a new one very easy.
