Our shrink tube wire labels are a great way to label each connector coming out of a controller. The tube fits over your wire, and when heated, will shrink down to wrap it tightly. The text on the wrap clearly signifies the voltage and the number of the connector it is attached to. We carry five different colors: yellow, red, blue, green, and white. This allows you to use different colors to create a color scheme to your specifications. We can customize wire wraps further for a small fee if you need something that is not carried on the site.
