Panduit DAP4BC-G0-5 4" Data Access Port

The Panduit DAP4BC-G0-5 provides organized cable entry for enclosures housing surveillance DVRs, network switches, and industrial controls. This 4-inch brush-style port maintains UL environmental ratings on NEMA-rated cabinets while routing power, data, and fiber runs through a single sealed opening. Security integrators use it to preserve Type 4/4X ratings on outdoor camera equipment boxes; datacenter installers deploy it in rack cabinets to manage high-density fiber and copper without compromising airflow or fire ratings; industrial automation techs rely on it to keep UL508A compliance when wiring control panels. Each unit ships individually packaged and carries CSA certification for Canadian installations.

Key Features

UL Listed to UL50, UL50E standards for Type 1, 3R, 4, 4X, 12, and 13 enclosures

UL508A rated for industrial control panel applications

CSA C22.2 NO. 14-13 and NO. 94.1/94.2 certified

4-inch diameter opening accommodates multiple cable bundles

Brush grommet design seals around cables to maintain environmental protection

Single-unit packaging for per-enclosure ordering

The DAP4BC-G0-5 uses a brush-style insert that flexes around cable bundles from 1/4" single runs up to full 4" conduit fills. Unlike knockout plugs with fixed cable holes, the brush design adapts to mixed cable types — coax, Cat6, fiber, and 18 AWG power — without custom drilling or multiple smaller fittings. The unit maintains the host enclosure's UL50 environmental rating by creating a friction seal that blocks dust, moisture, and insects while allowing airflow around cables to prevent heat buildup in equipment compartments. UL508A compliance makes it suitable for motor control centers and variable frequency drive cabinets where NEC 409 standards apply. The black powder-coated finish matches standard NEMA 1 and NEMA 4X enclosure colors.

Security integrators install these ports in outdoor PTZ camera junction boxes and parking-structure NVR cabinets where maintaining NEMA 4X ratings is critical for warranty and weather resistance. Datacenter and network teams use them in Wall-Mount Network Cabinets (WMNCs) and Enterprise Distribution Frames (EDFs) to route high-count fiber bundles and copper uplinks without the sharp edges of raw knockouts that can damage jacket insulation. Industrial automation installers depend on UL508A certification when wiring PLC racks, HMI enclosures, and safety relay panels — the listing allows inspection approval under NEC Article 409 for industrial machinery applications. The port installs in standard 4.5" knockout holes using a simple trim ring and internal retainer, requiring no special tools beyond a knockout punch for initial enclosure prep.

The DAP4BC-G0-5 meets UL50E supplemental requirements for outdoor and corrosive environments, making it suitable for coastal surveillance installations, chemical plant control rooms, and wastewater treatment SCADA cabinets. CSA certification covers installations in Canada under provincial electrical codes. Unlike generic hardware-store grommets, the Panduit listing allows the complete enclosure assembly — box, door, and cable entry — to carry a UL panel label, which satisfies AHJ inspection requirements and maintains integrator liability protection on projects requiring third-party certified components.
