Identify, match and Simplify with the Dotz™ Cord Identifier Kit. Never plug or unplug the wrong cord or cable again. This Kit makes the most complicated home theater, gaming or TV/phone/internet installations as easy as matching a shirt with a pair of pants. Match color, number and text on both ends of the cord to easily identify and match your electronic device connections. Perfect for receiver, monitor, TV, Blu-Ray player, cable box, stereo/speaker system, gaming, network and coaxial cable wiring behind walls, on separate floors or in different rooms. Choose one of two Cord Identifier sizes to fit around a full large range of cord and cable diameters. From USB to HDMI and power cables this Kit covers it all. Simply punch out one of the Inserts (12 colored and numbered combinations to choose from), write the device name or location on it and snap around the cord end. Repeat for the other cord end. Apply a matching sticker to the device's input or output and plug in the cord. For future reference and convenience record your identification method with a corresponding sticker on the included Device Chart. Changing out a device or adding a new one will never be so easy.
