12RU CAB WLL 4.5RS 19W INC SFD 15in CTR SEC

The AtlasIED 312-15 is a stand-alone wall-mount equipment cabinet designed around a 19-inch-wide rack opening. It provides 12RU of rack space, adjustable rails, and a 15-inch usable center-section depth. Its overall enclosure measures 24 inches high, 20 5/8 inches wide, and 21 1/2 inches deep, providing a clearly defined format for equipment planning and installation.

Ideal Use Cases

This model is suited to installations that require 12RU of equipment capacity in a wall-mounted cabinet rather than a floor-positioned rack. The 15-inch usable depth establishes the primary equipment-fit limit, while the adjustable rails allow the rail position to be configured for compatible components. It is appropriate when the available wall area can accommodate the cabinet’s 24-inch height, 20 5/8-inch width, and 21 1/2-inch overall depth.

The 312-15 is especially relevant when a project calls for a 19-inch rack opening but does not require more than twelve rack units. Equipment dimensions, connector clearance, cable routing needs, and mounting depth should be checked against the cabinet before installation.

Why Choose This Model

The central advantage of the 312-15 is its specific combination of rack capacity and depth. Twelve rack units provide a defined amount of vertical equipment space, while the 15-inch center section supports compatible equipment within that usable-depth limit. Adjustable rails add another practical configuration point, allowing their placement to be aligned with the requirements of the equipment being installed.

The published dimensional data also makes it possible to plan the surrounding space accurately. The 21 1/2-inch overall cabinet depth should be used when checking room clearance, even though the center section offers 15 inches of usable depth. The 20 5/8-inch overall width and 24-inch height should likewise be considered when selecting the installation location.

Installation and Integration

Before mounting the cabinet, confirm that the intended wall position provides enough clearance for its full external dimensions. Equipment should be evaluated individually for compatibility with the 19-inch opening, available rack-unit capacity, adjustable rail arrangement, and 15-inch usable depth. Rear connectors, attached cables, and any required installation clearance can affect fit even when the main equipment chassis is less than 15 inches deep.

The source data lists a shipping weight of 77.00 pounds, or 34.93 kilograms. This is a shipping specification rather than an installed cabinet weight or load rating, so it should be used for receiving and handling planning only. Mounting hardware, cabinet load capacity, and included accessories are not identified in the supplied information and should be confirmed separately before installation.

Performance Highlights

The 312-15 provides twelve rack units within a cabinet measuring 24 inches high. Its adjustable rails support installation flexibility for compatible rack equipment, while the 15-inch center section defines the available usable depth. The external depth of 21 1/2 inches distinguishes the cabinet’s total projection from its internal equipment allowance, an important consideration for both component selection and room planning.

A 60-month warranty period from the date of purchase is specified, giving the model a clearly stated coverage duration. No electrical, cooling, acoustic, or environmental performance ratings are provided in the source data.

What Makes It Different

This cabinet is identified by a focused set of installation characteristics: a stand-alone wall-mount configuration, 12RU capacity, a 19-inch-wide opening, adjustable rails, and a 15-inch-deep center section. These details differentiate it by fit and format rather than by electronic features. The adjustable rail design is particularly useful when fixed rail placement would not match the mounting requirements of compatible equipment.

The model number 312-15 also corresponds directly to the supplied 15-inch center-section depth, making the depth specification easy to identify during project planning. Its complete published dimensions help distinguish usable equipment depth from the space occupied by the cabinet itself.

Final Assessment

The AtlasIED 312-15 is a precisely specified choice for projects requiring a 12RU wall-mounted rack cabinet with adjustable rails and 15 inches of usable depth. Its 19-inch opening addresses compatible rack equipment, while the documented external dimensions provide the information needed for preliminary placement planning. Confirm equipment depth, connector clearance, mounting requirements, load capacity, hardware, and accessory needs before installation, as those details are not included in the supplied product data.
