Panduit XG-DRSP645B FlexFusion Split Hinged Door

The Panduit XG-DRSP645B is a perforated split hinged door engineered for 600mm-wide, 45RU FlexFusion cabinets in datacenter and network closet deployments. With 80% open perforation and a mechanical key lock, this door balances thermal management requirements with physical security—critical for high-density equipment racks running switches, servers, and UPS systems that demand unobstructed airflow while maintaining controlled access. The split-hinge design enables installation in tight aisle configurations where full-swing doors would block adjacent racks or create clearance conflicts, and the factory black powder-coat finish integrates with standardized datacenter aesthetics.

Key Features

80% open perforation pattern optimizes airflow for high-wattage equipment cooling

Split hinged design eliminates swing-clearance issues in dense row deployments

Mechanical key lock standard; accepts optional 3-digit combo, smart handle, HID, or HID/keypad upgrades

600mm width × 45RU height (81.99" / 2082.6mm tall) matches full-height FlexFusion cabinet specs

RoHS compliant construction for regulated facility installations

Datacenter managers and IT installers spec perforated doors like the XG-DRSP645B to prevent the thermal stratification that solid doors create in enclosed racks. The 80% perforation ratio—verified through Panduit's airflow testing—supports equipment that pulls 5–10kW per rack without requiring expensive supplemental cooling infrastructure. The split-hinge mechanism divides the door vertically, allowing each half to open independently in 90° or 180° configurations; this is essential when rack rows sit closer than 48" apart or when rear-door installations face walls in network closets. Field techs can service front-mounted patch panels or replace failed PSUs without repositioning adjacent cabinets.

The door ships with a mechanical key lock and accepts Panduit's modular security upgrades without requiring replacement hardware. Facilities requiring audit trails can retrofit the Smart Rack Security Handle (electronic logging), HID proximity readers for badge-controlled access, or combination HID/keypad assemblies that enforce two-factor authentication. The lock mechanism mounts to a universal bracket that accommodates any of these options, eliminating the need to stock multiple door SKUs for different security postures. Installers mount the door to FlexFusion frames using the included hinge-pin hardware; the split design distributes weight evenly across both hinges, preventing the sag issues common with oversized single-panel doors on tall enclosures.

The perforated steel construction meets RoHS compliance requirements for installations in California, EU-regulated facilities, and DoD contracts that prohibit restricted substances. The black finish resists fingerprints and matches Panduit's NetRunner cable management and FlexFusion frame components for unified rack-system branding. This door is the specified choice for integrators building out colocation cages, enterprise server rooms, or campus IDF closets where equipment density, access control, and cooling efficiency must all meet institutional standards without requiring custom fabrication.
