    A flexible enclosure solution.

    Sometimes, standard enclosure sizes just won’t cut it. Modular enclosures are used in situations where space is at a premium, as the different components of the modular system can be moved around to efficiently optimize a given amount of space. Like any electrical cabinet, modular enclosures protect your people and your devices from danger and damage. Modular electrical cabinets are used throughout a variety of industrial and commercial applications and are particularly common in the telecommunications industry.

    Advantages of modular enclosures.

    Modular enclosures are available in a variety of NEMA ratings for both indoor and outdoor use, though they tend to be more popular as a space-saving enclosure in indoor applications. Stainless steel enclosures and fiberglass enclosures can both be modular. Modular enclosures also give you much more flexibility in terms of details like mounting provisions, color and finish, size, material, and more. Thanks to their quick installation time and easy configuration, modular enclosures can fit just about anywhere all while effectively
