Never plug or unplug the wrong cord or cable again. Home Entertainment Cord Identifer Kit makes the most complicated home theater, gaming or tv/phone/internet installations as easy as matching a shirt with pants. Match color, number and text on both ends of the cord to easily see your electronic device connections, visible even in low-lit areas. Perfect for receiver, monitor, tv, Blu-Ray player, camcorder, cable box, stereo/speaker system, gaming, internet and coaxial cable wiring behind walls, on separate floors or in different rooms. Choose one of two cord identifer sizes to fit around standard cord and cable diameters; the jumbo identifier is perfect for HDMI cables. 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. Record with a corresponding sticker on the included device chart to have a convenient reference when changing out a device or adding a new device.
