Cord identifier kit makes sure you never plug or unplug the wrong cord or cable again. Cord identifiers let you match the color, number and text on both ends of the cord to easily see your electronic device connections. Two sizes are included to fit around standard cord and cable diameters as well as HDMI cables. The included device chart allows you to record your identification method with a corresponding sticker for convenient reference in the future. Cord identifier kit is perfect for a 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.
