Panduit DAP4BC-G0-5U 4 Inch Data Access Port

The Panduit DAP4BC-G0-5U delivers a code-compliant solution for routing high-density cable bundles through control panels, server racks, and enclosure walls. Designed for commercial data centers, industrial automation cabinets, and enterprise network installations, this 4-inch data access port provides a clean, protected transition point that meets UL50, UL50E, UL508A, and CSA C22.2 NO. 14-13 standards. Integrators working on projects requiring third-party inspections or compliance documentation will appreciate the comprehensive certification coverage spanning both general enclosure applications (UL50) and environmental ratings (UL50E). The port accommodates fiber trunks, Cat6A bundles, power feeds, and mixed-media runs while maintaining the NEMA integrity of the host enclosure, eliminating the improvised cutouts and rubber grommets that fail inspection or degrade over time.

Key Features

• UL Listed to UL50, UL50E, and UL508A standards plus CSA C22.2 NO. 14-13 and NO. 94.1/94.2 certification for comprehensive North American compliance
• 4-inch diameter opening sized for high-density cable bundles including 48-fiber trunks, multi-pair Cat6A runs, and hybrid media installations
• Engineered mounting flange integrates with standard knockout patterns in control panels, server racks, and NEMA-rated enclosures
• Brush-style or modular insert compatibility allows field customization for specific cable types and fill densities
• Maintains environmental ratings when properly installed in UL50E-compliant enclosures, critical for outdoor telecom cabinets and industrial environments
• Single-unit packaging supports small deployments and retrofit projects without forcing bulk purchases

Data access ports address a persistent challenge in professional network and control system installations: how to route cables into and out of enclosed equipment without compromising the enclosure's protective rating or violating electrical codes. The DAP4BC-G0-5U solves this with a purpose-built assembly that replaces the knockout slug with a secure, inspector-approved transition. The 4-inch diameter accommodates substantial cable counts—integrators regularly pass 12 to 24 Cat6A cables, or equivalent fiber and power combinations, through a single port—while the brush or modular insert design allows individual cables to enter at different points rather than forcing a single bundled entry. This flexibility is essential in live environments where circuits are added over time, or in retrofit scenarios where existing cables must remain undisturbed while new runs are pulled. The UL508A certification is particularly relevant for industrial control panels serving building automation, access control head-end equipment, and surveillance NVR/server installations, where the port often serves as the demarcation point between field wiring and enclosed electronics. CSA C22.2 NO. 14-13 coverage ensures compatibility with projects requiring Canadian electrical code compliance, common in cross-border enterprises and multinational data center operators.

Installation is straightforward for integrators familiar with standard enclosure practices. The port mounts from the exterior side of the panel using the factory knockout or a field-cut 4-inch hole, with the flange secured via screws or clips depending on the specific enclosure construction. Once the mechanical attachment is complete, cables are routed through the central opening, and the brush insert (if used) is pressed into place to provide a flexible seal around the bundle. The brush fibers are dense enough to block dust, insects, and incidental moisture while remaining pliable enough to accommodate cables of varying diameters without chafing the jackets. This is a meaningful advantage over solid grommets, which either fit tightly around a specific bundle size (and tear during future additions) or fit loosely (and compromise the seal). For high-security or harsh-environment projects, integrators can specify modular inserts with compartmentalized slots, ensuring each cable occupies a defined position and the remaining openings stay sealed. The UL50E environmental rating applies when the port is installed per Panduit's instructions within a UL50E-listed enclosure, maintaining Type 1, 3R, 4, or 12 performance depending on the host enclosure's rating. This compliance is non-negotiable for outdoor telecom cabinets, rooftop equipment shelters, and factory-floor control panels exposed to washdown or airborne contaminants.

The Panduit DAP4BC-G0-5U is spec'd on projects where inspectors verify that every enclosure penetration carries a UL listing and where the engineer of record requires submittal documentation for closeout packages. The competitor part numbers listed in the spec sheet (P-P11#2R2-M3RF0, P-P11#3R2-H3R0, P-P11R2-K3RF3) indicate cross-reference compatibility in bid-spec environments, but the DAP4BC-G0-5U's comprehensive multi-standard certification and single-unit availability make it the pragmatic choice for integrators managing mixed projects across jurisdictions. If you're pulling cable into a control panel that will face AHJ inspection, or building out a data center where every component needs a submittal trail, this port delivers the documentation and performance the job demands.
