Middle Atlantic S12SDG – Single Bay 12SP Square Top Rack, Gray

Product Overview

The Middle Atlantic S12SDG is a single-bay, 12-space open-frame roll rack in gray finish with a square top design. It is built for AV integrators who need a portable, open-access equipment rack for smaller systems such as audio amplifiers, signal processors, and control equipment. The open-bay construction provides unrestricted front, rear, and side access for cabling and maintenance without removing panels or doors.

Product Description

The S12SDG provides 12 rack spaces (12U) in a single-bay roll rack configuration, suited for smaller AV systems, portable rigs, and fixed installations where a full enclosure is unnecessary. The square top accepts flat-panel monitors, mixers, or other surface-mounted equipment, making it practical as a working surface in addition to a rack enclosure. Casters (or leveling feet, depending on configuration) allow the rack to be repositioned without disassembly.

The open-frame design gives installers and technicians unrestricted access to all rack-mounted equipment from front and rear, which simplifies initial wiring and ongoing maintenance. Cable routing is straightforward without doors or side panels obstructing pass-through. The gray powder-coat finish matches standard Middle Atlantic rack color conventions and blends with typical AV and IT equipment environments.

The rack uses standard 10-32 threaded rails, accepting universal rack hardware without cage nuts. It is compatible with Middle Atlantic rack accessories including shelves, blanks, and power strips. For installations requiring a larger capacity or enclosed design, Creation Networks can recommend appropriate alternatives from the Middle Atlantic catalog.

Frequently Asked Questions

What is the difference between a square top and a flat top rack?

A square top rack has a flat, unobstructed top surface at the same level as the top rail, providing a usable work surface. Some rack styles have angled or sloped tops that are not practical as a work surface. The S12SDG square top accepts flat-panel displays, mixers, or accessories placed directly on top.

Can this rack be used as a fixed installation rather than a portable roll rack?

Yes. While the roll rack configuration is designed for mobility, the casters can be locked or the rack can be placed on leveling feet for semi-permanent or fixed installations.

Is this rack available in black finish?

The S12SDG is the gray finish variant. Middle Atlantic offers equivalent models in black finish. Contact Creation Networks for alternative finish options.

What accessories are compatible?

Middle Atlantic shelves, rack blanks, power strips, and lacing bars designed for the S-series roll racks are compatible. Contact Creation Networks for accessory recommendations.
