Middle Atlantic WRK-40SA-32 – 40U 32"D Stand-Alone Equipment Rack

Product Overview

The Middle Atlantic WRK-40SA-32 is a 40-space, 32-inch-deep stand-alone equipment rack built for commercial AV installation and IT infrastructure where a single self-contained enclosure meets the room's capacity requirements. Part of the WRK-SA Series, this 24-1/4-inch-wide floor-standing rack pairs a welded steel frame with standards-compliant 10-32 tapped rails, giving integrators a dependable mounting platform for AV processors, network hardware, and power distribution. Its 40 RU height balances equipment capacity against the ceiling clearance found in typical commercial equipment rooms.

Product Description

The WRK-40SA-32 provides 40 rack spaces (70 inches of usable mounting height) and a 32-inch interior depth, accommodating everything from 1U network switches and patch panels to deep-chassis servers, UPS units, and AV signal processors in a single elevation. Welded steel construction eliminates frame flex under full loading, and the factory-assembled enclosure reduces on-site setup time during commercial deployment. The EIA-standard 19-inch rail system uses 10-32 tapped threads compatible with directly threaded hardware, clip nuts, and rack screws from virtually every equipment manufacturer. Adjustable rear support rails reposition to match mixed equipment depths up to 32 inches, while open top and bottom entries give installers unobstructed conduit and cable routing paths from above or below. Internal vertical cable channels keep power and data wiring organized and separated, reducing interference between signal and power runs during AV integration. The stand-alone (SA) configuration is intended for installations where one self-contained rack is preferred over a ganged multi-bay row, keeping the footprint compact at 24-1/4 inches wide. Middle Atlantic's WRK accessory ecosystem — vented blanking panels, cable managers, pull-out shelves, and vertical PDU mounts — integrates natively with the rail system, so the entire rack build-out can be specified from one manufacturer. The WRK-40SA-32 is stocked and supported by Creation Networks, an authorized Middle Atlantic dealer; explore related enclosures in our Middle Atlantic collection.

Technical Specifications

Frequently Asked Questions

What is the difference between the WRK-40SA-32 and the WRK-40-32?

The SA designation indicates a stand-alone, single-bay unit. The WRK-40-32 (without SA) is the multi-bay version of the same 40 RU, 32-inch-deep rack, designed to gang side-by-side in rack rows.

Is this rack compatible with standard 19-inch rack equipment?

Yes. The WRK-40SA-32 uses EIA-standard 19-inch rails with 10-32 tapped threads, so it accepts standard rack-mount equipment from any manufacturer.

How does cable routing work during installation?

Open top and bottom entries allow conduit and cable runs from above or below, and internal vertical channels separate power from signal wiring — useful when an installation combines AV, network, and power distribution in one enclosure.

Does it support equipment of different depths?

Yes. Adjustable rear support rails reposition to match equipment depths up to the 32-inch interior, so shallow switches and deep servers can share the same rack.

Which Middle Atlantic accessories work with this rack?

The full WRK accessory line — vented blanks, cable managers, pull-out shelves, drawers, fan tops, and vertical PDU mounts — mounts directly to the WRK-SA rail system.

What warranty and support are available?

The rack is covered by Middle Atlantic's manufacturer warranty. Creation Networks, an authorized dealer, provides configuration assistance before purchase and ongoing support after delivery; contact our team for warranty details and project help.
