The CM2-U2ATT series from Legrand is a dual module solution designed to accommodate Avaya and Lucent telephone systems. These modules come in a variety of colors and are specifically engineered for wire ducting applications, making them ideal for installation in telecommunications closets and other structured cabling environments. If you're working on projects that require flexibility in color coding and need to support multiple vendor equipment, these modules are a solid choice.

One thing worth noting is their versatility in color options. This feature allows for easier identification and organization of different types of lines or services within a wiring closet, which can be particularly beneficial in larger installations where maintaining order is crucial. Engineers tend to reach for this when they need a reliable way to manage diverse telecom equipment from different manufacturers while keeping the aesthetic and organizational needs of the space in mind. The ability to customize the look of your installation can also contribute to a more professional appearance, which is often important in commercial and enterprise settings.
