Middle Atlantic A40-28CS – Boxed SR-40-28 Center Section

Product Overview

The Middle Atlantic A40-28CS is the boxed center section for the SR-40-28 pivoting rack, giving integrators a factory-direct way to source the core rack frame for a 40-space, 28-inch deep SR Series installation. It is the structural heart of the SR pivoting rack system, designed for in-wall and recessed AV equipment mounting in commercial environments. Specifying the center section on its own supports phased commercial deployment, replacement, and multi-room rollouts where SR Series components are ordered separately.

Product Description

Middle Atlantic's SR Series pivoting rack platform is a long-standing choice for integrators who need full rear access to rack-mounted equipment in space-constrained rooms. The A40-28CS supplies the SR-40-28 center section in boxed form, matching the 40 rack space height and 28-inch depth class of its parent rack. As the center section, it provides the equipment mounting structure around which the rest of the SR-40-28 assembly is built. This makes it the correct part to specify when a project calls for the core SR-40-28 frame, when standardizing rack hardware across multiple rooms, or when an existing center section needs replacement after damage or reconfiguration. Because it is a genuine Middle Atlantic component, rail spacing, hardware, and fit match the SR Series system it belongs to, which protects installation labor budgets on commercial integration work. Procurement teams can order it under the single SKU A40-28CS with factory packaging suited to jobsite delivery. For surrounding hardware, rack accessories, and other SR Series components, see our full Middle Atlantic collection. If you are unsure whether the center section alone meets your project scope, our AV design team can confirm the correct SR Series part set before you order.
