Panduit DAP4BC-G0-6 4-Inch Data Access Port

The Panduit DAP4BC-G0-6 is a UL-listed 4-inch data access port engineered for professional cable pass-through in security equipment racks, IT enclosures, AV cabinets, and raised-floor datacenters. This grommet-style port provides a clean, protected pathway for power and data cables crossing panel boundaries while maintaining compliance with UL50, UL50E, UL508A, and CSA C22.2 standards. The 4-inch diameter accommodates moderate to heavy cable bundles—sufficient for multi-camera trunk runs, PoE switch uplinks, or mixed low-voltage and fiber installations—without the cable-jacket abrasion and dust ingress common to unprotected knockout holes.

Key Features

4-inch clear opening handles bundled Cat6, fiber, and power cables in a single pass-through

UL50/UL50E rating ensures enclosure integrity for indoor non-hazardous environments

UL508A and CSA C22.2 NO. 14-13 compliance meets industrial control panel and commercial building codes

Snap-in or screw-mount design (depending on panel thickness) simplifies retrofit and new construction

Smooth bushing edge protects cable jackets during pulls and prevents long-term chafing on PoE or fiber runs

Data access ports solve the recurring problem of cable damage at panel entry points. Standard knockouts leave sharp edges that nick Cat6 jackets during installation and slowly abrade insulation over months of thermal expansion cycles. The DAP4BC-G0-6 installs into a 4-inch round or square cutout and presents a smooth, radiused surface that guides cables without snagging. In security deployments this matters for PoE camera trunk lines running from a switch rack to a plenum or conduit—any jacket breach risks moisture ingress, intermittent link failures, or voltage drop under full 60W PoE++ load. The port's UL50 rating maintains the enclosure's NEMA type classification, critical when the cabinet houses network switches, PoE injectors, or power supplies subject to local electrical inspection.

The 4-inch size is the middle ground for integrators: large enough to pass a dozen Cat6 cables plus a fiber trunk or two AC power cords, yet small enough to fit between studs or in the side panel of a standard 19-inch rack. It's the go-to size for IP camera head-end racks feeding multiple buildings, AV equipment closets serving conference rooms, or access-control panels pulling door strikes, card readers, and request-to-exit sensors. The port's CSA C22.2 NO. 94.1/NO. 94.2 certification confirms flammability and mechanical-strength testing, ensuring the bushing won't degrade or crack under the thermal cycling typical in equipment rooms with variable HVAC. Competitor parts listed in Panduit's cross-reference (P-R62 series) serve similar applications, but the DAP4BC-G0-6's UL508A industrial-control-panel rating extends its applicability to manufacturing-floor security installations where machinery-area cameras and intercoms share enclosures with motor controllers or PLCs.

Installation is straightforward: cut or punch a 4-inch hole in sheet metal (18–16 ga typical), plastic, or plywood, insert the port from the exterior side, and secure with the included snap ring or machine screws depending on panel thickness and vibration exposure. The bushing sits flush or slightly recessed, maintaining a professional appearance on customer-facing equipment. For raised-floor datacenters the port mounts in floor tiles or cable trays, managing the transition from under-floor conduit to overhead ladder rack without leaving cables resting on tile edges. In security rack applications pair it with Panduit's horizontal or vertical cable managers to maintain bend-radius compliance from the port to the switch—critical for 10GbE fiber or shielded Cat6A runs where tight bends degrade performance or violate TIA-568 installation standards.
