Panduit DAP4BC-G0 4 Inch Data Access Port

The Panduit DAP4BC-G0 is a 4-inch data access port designed to maintain UL50/UL50E environmental ratings in electrical enclosures, server cabinets, and industrial control panels while providing structured cable egress. This port solves the persistent challenge of routing high-density fiber, copper, and power bundles through enclosure walls without compromising NEMA/IP ratings or creating sharp-edge hazards that damage cable jackets during moves/adds/changes. Integrators installing rack-mount equipment in NRTL-rated enclosures, datacenter hot-aisle containment systems, or industrial automation cabinets gain code-compliant cable pass-through that preserves the enclosure's tested environmental classification.

Key Features

UL50/UL50E rated construction maintains enclosure environmental classification when properly installed in listed panels

4-inch diameter opening accommodates typical trunk cable bundles for 24-48 port switch deployments

UL508A compliance for industrial control panel integration in manufacturing and process-automation environments

CSA C22.2 NO. 14-13 and NO. 94.1/94.2 dual-certification for Canada and cross-border installations

Single-unit packaging for project staging and field serviceability

The DAP4BC-G0 ships with mounting hardware and installation instructions specific to maintaining UL50E ratings when installed in outdoor-rated enclosures. The 4-inch aperture is sized for common trunk cable bundles—twelve Cat6A cables, six LC duplex fiber assemblies, or mixed-media runs typical in converged IP surveillance and building-automation deployments. The port's smooth-edge design prevents jacket abrasion during cable pulls, a common failure point in retrofitted knockouts or filed openings that void enclosure listings and create NEC 110.3(B) violations during AHJ inspections. Installers working under NFPA 70 Article 312 (cabinets/cutout boxes) or Article 408 (switchboards/panelboards) can verify the data port maintains the enclosure manufacturer's IP/NEMA rating by cross-referencing UL50 certification against the enclosure's own listing.

Deploy the DAP4BC-G0 in telecommunications rooms where floor-mount racks require overhead cable entry while preserving plenum-rated ceilings, in industrial settings where PLC cabinets need segregated data/power routing to meet UL508A separation requirements, or in outdoor equipment shelters where UL50E environmental performance prevents moisture ingress at cable-entry points. The port is engineered for single-gang panel cutouts, streamlining retrofits into existing enclosures without requiring oversized openings that weaken structural integrity or disrupt interior component layout. CSA certification extends applicability to cross-border projects and Canadian provincial electrical codes that mandate CSA-certified components for legal installation.

UL50E outdoor rating differentiates this port from indoor-only cable grommets—the listing confirms performance under NEMA 3R/4/4X test conditions (rain, sleet, external ice formation, and hosedown). For integrators managing enclosure compliance across mixed indoor/outdoor deployments, the DAP4BC-G0 provides a single SKU that meets both UL50 (general) and UL50E (outdoor/wet location) standards, simplifying BOM management and field-stock inventory.
