About Rack Enclosures

Rack enclosures (rack cabinets, laboratory enclosures) are used to house standard 19 in. rack-mounted components or other standard-sized devices. They are designed to protect personnel from accidental injury and to prevent the ingress of environmental contaminants such as dust and water. Rack enclosures are rectangular or T-shaped, made from a variety of materials, and available in many different sizes, sealing configurations, and mounting styles. Length, width, and height are important dimensions to consider. Inside length, inside width, inside height, and sloped surface length are also important considerations. Length and height are measured vertically while rack enclosures are in the normal operating position. By contrast, width is measured horizontally. Depth equals the distance from the front to the rear of the rack cabinet. Normally, rack height is specified in U where 1U = 1.75 in.
