Panduit DAP3BC-S0-5U 3" Brush Data Access Port

Panduit DAP3BC-S0-5U 3" Data Access Port

The Panduit DAP3BC-S0-5U is a 3-inch brush-style data access port engineered for cable pass-through in enclosures, panels, and work surfaces where environmental integrity and UL compliance are mandatory. Designed for IT infrastructure, industrial control cabinets, and data center rack installations, this port maintains NEMA Type 1/12 ratings while accommodating high-density fiber, copper, and power cable bundles. UL Listed to UL50, UL50E, and UL508A standards, plus CSA C22.2 NO. 14-13 and NO. 94.1/NO. 94.2 certification, it meets the compliance requirements for commercial AV integrations, building automation systems, and industrial Ethernet deployments where inspection authorities require third-party-certified cable entry solutions.

Key Features

• 3-inch clear opening accommodates bundled cables up to 2.75" diameter including jacketed fiber trunk assemblies, Cat6A patch cords, and industrial connector shells
• Brush-style sealing system maintains dust and debris protection per NEMA Type 1/12 while allowing cable movement for adds/moves/changes without gasket replacement
• UL Listed to UL50, UL50E, and UL508A standards ensuring suitability for electrical enclosures, industrial control panels, and equipment racks subject to NEC Article 312 requirements
• CSA C22.2 NO. 14-13 and NO. 94.1/NO. 94.2 certified for installations under Canadian Electrical Code Part I and provincial inspection authority oversight
• Snap-in mounting design fits standard knockout holes and rectangular cutouts in 14-16 gauge steel and aluminum enclosures without separate trim rings or fasteners
• Low-profile bezel depth minimizes intrusion into shallow-depth network cabinets and wall-mount enclosures common in telecom rooms and IDF closets

The DAP3BC-S0-5U addresses a specific integration challenge in commercial security and IT infrastructure: how to route cables into sealed enclosures without compromising environmental ratings or failing inspection. Standard knockouts with rubber grommets or simple hole-and-edge-protector solutions cannot maintain NEMA Type 1 or Type 12 ratings once cables are pulled, creating liability during AHJ (Authority Having Jurisdiction) inspections and leaving equipment vulnerable to dust accumulation in warehouse, manufacturing, or outdoor-pedestal installations. Panduit's brush system uses densely-packed synthetic bristles that flex around cable jackets—from 28 AWG control wire up to 1-inch conduit or trunk cable—while maintaining a continuous barrier against particulate intrusion. Unlike split grommets that gap under cable tension or degrade from UV exposure in outdoor-rated enclosures, the brush filaments return to their sealed state even after repeated cable insertions, making this port suitable for live data centers and industrial sites where adds/moves/changes occur without taking equipment offline.

Integrators deploy the DAP3BC-S0-5U in three primary scenarios: data center server racks requiring top-of-rack or bottom-entry cable management with containment aisle compliance, industrial Ethernet cabinets housing managed PoE switches and UPS systems in manufacturing environments subject to Title 24 or OSHA electrical safety inspections, and commercial AV equipment racks in conference rooms or control rooms where building code requires listed enclosures for low-voltage wiring. The 3-inch diameter is deliberately sized for multi-cable bundles common in these applications—a typical installation might route six Cat6A cables, two LC duplex fiber patch cords, and one 14/3 AC power whip through a single port, replacing what would otherwise require three separate knockouts and three potential leak points. In retrofit scenarios, the snap-in design eliminates the need for panel removal or interior access, as the port can be installed from the exterior of an energized enclosure by enlarging an existing knockout to 3.25 inches with a step bit, then pressing the bezel into place until the retention tabs click. This single-person, no-fastener method reduces rack installation time compared to bolt-on grommets, a measurable advantage during cutovers or after-hours maintenance windows where minimizing downtime directly impacts SLA compliance.

UL50 and UL50E listings certify that this port maintains enclosure integrity per NEMA 250 specifications when installed per manufacturer instructions, meaning the brush seal performs equivalently to the base enclosure rating—typically Type 1 indoors or Type 12 in industrial environments with oil mist or non-corrosive dust. UL508A certification extends suitability to industrial control panels subject to NEC Article 409, a critical requirement for integrators installing access control panels, fire alarm sub-panels, or building automation controllers in mechanical rooms or IT spaces governed by electrical inspection. CSA certification mirrors these capabilities under Canadian code, ensuring cross-border projects—common for enterprise clients with US and Canada facilities—can standardize on a single SKU without separate product qualifications. The combination positions the DAP3BC-S0-5U as a spec-grade component for integrators whose project documents reference NEMA, UL, or CSA standards by number, delivering a solution that passes both design review and field inspection without substitution requests or variance applications.
