Panduit AR4PCN96WH Adjustable Depth 4-Post Rack

The Panduit AR4PCN96WH delivers the mounting flexibility datacenter and security installers need when equipment depth varies across deployments. This adjustable-depth 4-post rack supports mounting depths from 23" to 42" in half-inch increments, eliminating the need to stock multiple fixed-depth frames. At 52 rack units tall with square-hole cage nut rails on all four posts, it accommodates deep servers, UPS systems, network switches, NVRs, and cable management infrastructure in a single white powder-coated steel frame. The front and rear structural posts accept all Panduit vertical cable managers, PDU brackets, waterfalls, and vertical tie-off panels, making this rack the foundation for clean, compliant installations in telco rooms, NOCs, and enterprise server closets.

• Structural posts accept PDU brackets, waterfalls, and accessory mounting hardware
• 20.3" overall width fits standard equipment room layouts
• RoHS compliant for environmentally responsible installations

The adjustable-depth design solves a persistent problem in mixed-equipment environments. Security integrators installing 16-channel enterprise NVRs alongside network switches and KVM gear often face mounting depth mismatches—recording servers with hot-swap drive bays may require 30" or more rail-to-rail clearance, while 1U switches need only 24". Fixed-depth racks force you to choose between wasted space or multiple frame types. The AR4PCN96WH's half-inch depth increments let you dial in the exact mounting plane for each install, then lock the adjustment with structural hardware. Front and rear posts use square punched holes on 0.625" vertical spacing per EIA-310-E, accepting standard cage nuts for tool-free equipment mounting. The 52 RU height provides enough vertical capacity for a full-height installation with 42U of active equipment plus cable management overhead at top and bottom. Steel construction with powder-coated finish meets UL 2416 safety requirements for fire resistance and structural integrity under load—critical when you're mounting 800+ pounds of servers, batteries, and switching gear in a single frame.

Cable management integration is where this rack separates from commodity open-frame alternatives. The front and rear structural posts feature dedicated mounting provisions for Panduit's vertical cable manager lineup—no adaptor brackets or custom drilling required. When you're running 96-strand fiber bundles, Cat6A copper trunks, and power distribution to 40+ RU of active gear, cable pathway capacity becomes the limiting factor. Panduit vertical managers mount directly to the rack's structural posts, creating dedicated wire lanes that keep signal cables separated from power and provide bend-radius protection for fiber. The posts also accept PDU mounting brackets, letting you position power distribution vertically along the side or horizontally across the rear without consuming RU space or blocking airflow. For fiber-intensive deployments, waterfall brackets and vertical tie-off panels bolt directly to the same mounting holes, providing transition points where backbone cabling enters the rack from overhead or underfloor pathways. This level of accessory integration is what lets you build a 52U installation that's still serviceable two years later—cables routed in dedicated lanes, labeled, and protected from the "pull harder" maintenance approach that destroys bend radius.

The white powder-coat finish is specified for visibility in finished spaces where black open-frame racks would stand out. Enterprise telco rooms, hospital IT closets, and university datacenter expansions often have white or light-colored walls, and a white rack blends into the environment while still providing full structural capacity. The finish is applied over steel substrate, so you're not trading durability for aesthetics—the frame still meets UL 2416 structural and fire-resistance requirements, and the coating resists chipping during equipment installation. Overall width of 20.3" fits standard 24" tile layouts in raised-floor datacenters and leaves clearance for side-mounted cable managers in equipment rooms built to minimum depth specs. When you're installing in a renovated office space converted to a NOC, that 20" width often makes the difference between fitting the rack through a 36" doorway or cutting drywall. The square-hole cage nut rails are stamped on 0.625" spacing across the full 52 RU height, so you have mounting flexibility for oddball 1.5U and 2.5U equipment that doesn't land on integer rack-unit boundaries. UL 2416 listing and EIA/ECA-310-E compliance ensure the rack meets structural and safety requirements for insurance and municipal building inspections—particularly important in medical, educational, and government facilities where non-listed equipment can fail code review and delay project acceptance.
