Panduit R4P36CN96WH 4-Post Rack, 52RU, 36 in. Deep, Cage Nut E-Rails, White

The Panduit R4P36CN96WH delivers the structural rigidity of a cabinet with the airflow and accessibility of an open rack—critical when you're racking deep switches, UPS units, or patch panel arrays that need front and rear access without door constraints. This 52RU frame is built for datacenters, telecom closets, and security NOCs where equipment depth exceeds shallow 2-post limits and you need UL-verified load capacity for fully populated racks. At 36 inches deep with adjustable cage nut rails, it accommodates modern enterprise gear while maintaining standard 19-inch EIA mount spacing. The white powder-coated steel finish integrates with clean-room and healthcare IT environments where black racks clash with facility aesthetics.

Key Features

• 52RU vertical capacity with 23.25 in. overall width, 19 in. standard EIA mount spacing
• 36 in. adjustable depth accommodates deep servers, switches, and UPS units
• Cage nut E-rails with printed RU numbering for tool-free equipment mounting
• UL 2416 listed for 2,500 lb static load—handles fully populated racks with battery backup
• Welded steel construction with white powder-coated finish for durability and corrosion resistance
• EIA/ECA-310-E compliant universal mounting hole spacing
• Compatible with Panduit cable managers, PDUs, and rackmount accessories
• RoHS compliant for regulatory adherence in commercial installations

The 2,500-pound UL 2416 rating is the critical spec when you're loading racks with dense blade servers, storage arrays, or battery cabinets—underrated racks fail inspection or worse, collapse under load. Panduit's welded steel frame construction eliminates the flex and sway common in bolt-together designs, and the cage nut rail system gives you infinite vertical adjustment without drilling or tapping. The printed RU numbering on the rails speeds up equipment placement and eliminates the tape-measure guesswork that leads to misaligned gear. At 36 inches deep, this rack handles modern switches and routers with rear-mounted power supplies, deep-chassis UPS units, and cable management arms without the gear-hanging-off-the-back problem you get with 30-inch frames. The adjustable rail design also lets you fine-tune front-to-back positioning for equipment with non-standard mounting ears or airflow requirements.

In datacenter and telecom applications, the open-frame design maximizes airflow compared to enclosed cabinets—essential when you're running high-wattage switches or servers in hot-aisle configurations. The white powder-coat finish resists chipping during equipment changes and matches the aesthetic requirements of healthcare IT closets, clean rooms, and corporate network hubs where black racks stand out. Panduit's accessory ecosystem integrates directly: vertical and horizontal cable managers mount to the frame without adapters, PDUs attach to the uprights, and blanking panels snap into the cage nut rails to maintain airflow separation. For security integrators, this rack works for NVR clusters, PoE switch stacks, and UPS redundancy arrays where you need the mounting flexibility of a 4-post frame but don't want to manage cabinet doors and side panels during service calls. The EIA/ECA-310-E compliance ensures compatibility with any rackmount gear—servers, switches, patch panels, KVMs, cable managers—from any manufacturer, eliminating the compatibility gambles you get with proprietary rail systems.

UL 2416 and EIA/ECA-310-E certification means this rack passes the structural and safety thresholds required by commercial building codes and datacenter operators—critical for installs subject to inspection or where liability is a concern. The cage nut rail system is faster than square-hole racks during initial deployment and easier to reconfigure when equipment changes, and the 52RU height maximizes vertical density in standard ceiling-height IT spaces without custom framing. RoHS compliance clears the regulatory bar for federal, healthcare, and international projects where non-compliant materials trigger change orders. For integrators managing multi-site rollouts, the Panduit accessory compatibility gives you a single-vendor BOM for racks, cable management, and power distribution—reducing SKU sprawl and simplifying sparing. This is the rack for projects where structural integrity, load capacity, and standards compliance are non-negotiable.
