Panduit AR4PCNWH Adjustable-Depth 4-Post Rack, 45RU, Cage Nut Rails
The Panduit AR4PCNWH solves the recurring datacenter and equipment-room challenge of accommodating mixed equipment depths without stocking multiple rack SKUs. This 45RU open-frame rack adjusts from 23" to 42" mounting depth in half-inch increments, letting you standardize on a single part number while supporting everything from shallow network switches to deep UPS systems and server chassis. Square-hole cage nut equipment rails on front and rear structural posts accept standard 19-inch rack-mount gear and integrate directly with Panduit's full line of vertical and horizontal cable managers, PDU brackets, waterfalls, and vertical tie-off panels. White powder-coated steel construction meets EIA/ECA-310-E dimensional standards and carries UL 2416 listing for safety-critical installations.
Key Features
- Adjustable 23"–42" depth in 0.5" increments — one SKU covers shallow networking gear, mid-depth servers, and deep storage arrays without adapter kits or custom rails
- 45RU (78.75") vertical capacity — full-height rack maximizes floor-space efficiency in datacenter rows and equipment closets
- Square-hole cage nut rails on front and rear posts — tool-free cage nut insertion, faster equipment changes than tapped or threaded holes
- 20.3" (515.9mm) overall width — standard footprint fits 24" tile layouts and conventional rack rows
- Native Panduit accessory integration — structural posts designed for Panduit vertical cable managers, power strips, and tie-off hardware without aftermarket brackets
- White powder-coat finish — clean aesthetic for customer-facing NOCs, broadcast facilities, and AV integrations where visible racks must match décor
- EIA/ECA-310-E, UL 2416, RoHS — meets North American datacenter standards and European environmental compliance for multinational deployments
Depth adjustability is the defining advantage for integrators managing heterogeneous equipment stacks. A typical security/IT installation might combine 12" shallow PoE switches, 24" 2U servers, 30" UPS units, and 36" storage shelves in the same rack — the AR4PCNWH accommodates all four without rail adapters or wasted space. Front and rear posts slide independently and lock at each half-inch position with captive hardware, so you can fine-tune equipment placement for optimal cable routing and airflow without disassembling the frame. The square-hole cage nut design eliminates the need for drilling or tapping; cage nuts snap into the square perforations by hand and hold M6 or 10-32 screws securely under load. This translates to faster equipment swaps during maintenance windows and simpler field modifications when adding midspan injectors, patch panels, or KVM shelves between existing gear.
Integrators deploying structured cable management will appreciate the rack's native compatibility with Panduit's vertical manager ecosystem. The structural side posts accept Panduit vertical managers (single-sided and dual-sided models) via direct bolt-on attachment, creating a unified cable runway alongside active equipment without third-party mounting rails. PDU brackets, horizontal waterfalls, and vertical tie-off panels mount to the same posts, so you can build a fully documented, code-compliant cable plant inside the rack footprint. For IP surveillance and physical-security installations, this means cleaner separation of PoE uplink trunks, camera home-runs, and access-control I/O without zip-tie tangles or unsupported cable weight sagging across equipment intakes. The white powder-coat finish serves both functional and aesthetic roles: the smooth surface resists corrosion in climate-controlled environments, and the neutral color blends into white-walled NOCs, broadcast studios, AV closets, and corporate lobbies where black racks would visually dominate the space.
Compliance certifications matter when your installation must pass datacenter audits, insurance inspections, or municipal electrical reviews. The AR4PCNWH's EIA/ECA-310-E conformance guarantees that mounting-hole spacing, post width, and RU dimensions match the universal 19-inch standard, so every piece of rack-mount gear from any manufacturer will physically fit without adapter plates. UL 2416 listing covers the structural and electrical safety of the rack frame itself, a requirement for installations in hospitals, schools, government facilities, and any site where the authority having jurisdiction demands third-party safety certification. RoHS compliance opens European and California markets by restricting hazardous substances in the steel and coating. For integrators bidding municipal contracts, healthcare projects, or Fortune-500 datacenter builds, these certifications are not optional — they are bid qualifications. The AR4PCNWH checks every box without requiring spec-exception paperwork or field testing, reducing project risk and accelerating AHJ approval.
