Middle Atlantic WRK-40-27LRD – 40RU 27" Deep Multi-Bay Rack, Less Rear Door

Product Overview

The Middle Atlantic WRK-40-27LRD is a 40-space, 27-inch deep floor-standing equipment rack built for multi-bay AV installations where racks are ganged together and rear access is handled at the row level, so the rear door is omitted. Its wider 24-1/4" footprint accommodates thick cable bundles and promotes cooling airflow that a standard-width enclosure cannot match. Integrators specifying commercial AV rack systems for equipment-dense head ends will find the WRK series a dependable mounting platform with seismic certification available for code-driven projects.

Product Description

The WRK series was engineered with a wider footprint specifically for mounting equipment with thicker cable bundles that would be difficult to fit in a basic rack. At 40 rack spaces tall and 27 inches deep, the WRK-40-27LRD provides the vertical capacity and equipment depth needed for video processors, amplifiers, network switches, and signal distribution gear in a single bay. Fully welded construction delivers the structural strength required for heavy commercial deployments, and the series offers seismic certification for installations in jurisdictions that require it. The 24-1/4" overall width creates dedicated space on either side of the rackrail for side cabling or additional cooling airflow. Standard front and rear adjustable 10-32 threaded rackrail with numbered spaces simplifies equipment installation and load planning, while the extra-wide rackrail features cable pass-throughs to facilitate clean front-to-rear cabling. Convenient lacing points and slotted rail brackets support disciplined cable management throughout the enclosure. The less-rear-door (LRD) configuration suits multi-bay rows, equipment rooms with rear walkways, or projects pairing the rack with a separately specified door. Open or removable sides allow ganged configurations and easy access during integration. Pair this rack with power, thermal, and cable management accessories from our Middle Atlantic collection for a complete rack build.

Technical Specifications

Frequently Asked Questions

What does the LRD designation mean on this rack?
LRD stands for less rear door. The WRK-40-27LRD ships without a rear door, which suits multi-bay rows, rear-walkway equipment rooms, or projects adding a door separately.

Can the WRK-40-27LRD be ganged with other racks for a multi-bay installation?
Yes. The WRK series is designed for multi-bay installations, and the open or removable sides allow racks to be ganged side by side with shared cable pathways.

How does the wider footprint help with AV integration?
The 24-1/4" overall width leaves room beside the rackrail for thick cable bundles and vertical cable management, and it improves cooling airflow around mounted equipment.

Is the rackrail adjustable for different equipment depths?
Yes. Both front and rear 10-32 threaded rackrails are adjustable, and numbered spaces make rack elevation drawings easy to execute in the field.

Does this rack meet seismic requirements?
The WRK series offers seismic certification. Confirm the certification documentation required by your jurisdiction with your project engineer before specifying.

Is this rack suitable for IT and network equipment as well as AV gear?
Yes. The 27-inch depth and standard 10-32 threaded rail accommodate network switches, servers, and signal processing equipment commonly deployed in commercial AV systems.

What warranty and support apply to this product?
Middle Atlantic racks are covered by the manufacturer's warranty, and Creation Networks provides pre-sale configuration help and post-sale support for your rack build.
