Panduit R4P42CN96 52RU 4-Post Open Rack with Cage Nut E-Rails

Overview

The Panduit R4P42CN96 is a 52RU, 41.5-inch-deep 4-post open rack built for data centers, server rooms, and network equipment deployments where you need cabinet-grade stability without sacrificing front-and-rear accessibility. At 23 inches overall width with a standard 19-inch EIA mounting field, it drops into any conventional rack row without requiring custom spacing or adapter rails. The welded steel frame is UL listed for 2,500 pounds — enough headroom to fully populate heavy switching, compute, and storage equipment without worrying about structural limits. If you're planning a mixed equipment room or a dense network closet, the 4-post open rack format gives installers unrestricted cable access and faster equipment swaps compared to a closed cabinet.

Key Features

• 52RU of usable space: 52 rack units gives you enough vertical real estate to populate a full mix of 1U servers, 2U switches, and patch panels without resorting to a second rack mid-project. For a typical enterprise edge deployment, that translates to a complete compute-and-networking stack in a single footprint.
• 41.5-inch depth with adjustable mounting rails: The 41.5-inch depth accommodates modern deep servers and storage arrays — most 2U rack servers run 28–32 inches deep, so there's genuine rear clearance for cable management and airflow. Adjustable rails mean you're not locked into a single depth position as equipment changes over time.
• Cage nut EIA universal mounting hole spacing: Cage nut E-rails accept standard 10-32, 12-24, or M6 cage nuts, so every piece of gear you already own mounts without adapter kits. Printed unit numbering on the rails eliminates counting errors during dense installations — a small detail that saves real time on 40+ unit builds.
• UL listed for 2,500 lb static load: The UL 2416 listing isn't just a checkbox — it means the welded steel frame has been third-party verified to hold 2,500 pounds. That's critical for insurance and facilities compliance in commercial builds, and it gives you margin when equipment weights add up across a full 52RU population.
• Welded steel construction, powder-coated black finish: Welded (not bolted) frame construction means no rack creep or joint flex under load. The powder-coat finish resists corrosion and handles the inevitable scuffs from equipment installation without flaking — relevant in any environment with repeated hardware refreshes.
• EIA/ECA-310-E and RoHS compliant: EIA/ECA-310-E conformance ensures interoperability with any standard 19-inch equipment — no surprises with rail spacing or hole patterns. RoHS compliance satisfies procurement requirements for restricted-substance regulations in government and public-sector projects.
• Compatible cable managers and accessories ecosystem: Panduit's rack accessory line — horizontal and vertical cable managers, brush strips, blanking panels — integrates directly with the R4P42CN96 rail design. Specifying accessories from the same Panduit rack and enclosure line avoids the fitment problems that come with mixing brands on cable management hardware.

Integration and Compatibility

The R4P42CN96 follows standard EIA/ECA-310-E rack geometry, making it compatible with equipment from any major vendor — switching, compute, storage, KVM, and patch panel infrastructure. The cage nut rail design accepts the full range of standard fastener sizes used in enterprise hardware. Adjustable rail depth positions support both shallow networking gear and deep server chassis in the same rack. Cable managers, vertical organizers, and blanking panels from the Panduit accessory portfolio are designed to mount directly to this rack's rail profile, supporting structured cabling buildouts in network infrastructure environments.

Frequently Asked Questions

Q: What is the load capacity of the Panduit R4P42CN96?

A: The R4P42CN96 is UL listed (UL 2416) for 2,500 pounds static load capacity. This is a third-party verified rating on the welded steel frame.

Q: What mounting hardware does the R4P42CN96 use — square hole or cage nut?

A: The R4P42CN96 uses cage nut E-rails with EIA universal mounting hole spacing. Standard 10-32, 12-24, or M6 cage nuts fit the rail pattern, compatible with virtually all 19-inch rack-mount equipment.

Q: What are the exact dimensions of the R4P42CN96?

A: The rack is 52RU tall, 23.25 inches (591mm) overall width with a 19-inch standard EIA mounting field, and 41.5 inches deep. Mounting rails are adjustable within that depth envelope.

Q: Is the R4P42CN96 RoHS compliant?

A: Yes. The R4P42CN96 meets RoHS compliance requirements, as well as UL 2416 and EIA/ECA-310-E standards.

Q: Does the R4P42CN96 work with Panduit cable management accessories?

A: Yes. Panduit's cable managers and rack accessories are designed to integrate with the R4P42CN96 rail profile. Horizontal and vertical cable managers from the Panduit cabinets and enclosures line mount directly to this rack.

Q: Is the R4P42CN96 an open rack or a closed cabinet?

A: The R4P42CN96 is an open 4-post rack — no side panels, doors, or roof. This provides unrestricted front and rear access for cabling and equipment installation, while the 4-post frame delivers the structural rigidity of a cabinet.
