Panduit DAP4BC-G0-4 4" UL-Rated Data Access Port

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

The Panduit DAP4BC-G0-4 is a 4-inch data access port engineered for clean cable entry into UL-rated enclosures and industrial control panels. When you're routing power, network, and sensor cables into security system mains, network equipment cabinets, or industrial control enclosures, this port maintains UL50/50E environmental ratings and UL508A industrial control panel compliance without the mess of knockouts or conduit fittings. The 4-inch opening accommodates bundled cable runs up to roughly 3.5 inches in effective diameter, making it suitable for multi-drop installations where you're pulling 8–12 Cat6 cables, multiple 18/2 power pairs, and coax runs through a single penetration point. CSA C22.2 NO. 14-13 and NO. 94.1/94.2 certification ensures compatibility with Canadian electrical code requirements for industrial enclosures and commercial security installations.

Key Features

• 4-inch diameter opening handles bundled cable groups up to ~3.5" effective diameter — accommodates 8–12 Cat6 cables, multiple power pairs, and coax in a single penetration
• UL50 and UL50E rated for Type 1, 3R, 4, 4X, and 12 enclosures — maintains environmental protection in outdoor, wet location, and washdown environments
• UL508A industrial control panel listed — meets requirements for control cabinets housing access control panels, PoE injectors, and power distribution units
• CSA C22.2 NO. 14-13 and NO. 94.2 certified — complies with Canadian Standards Association requirements for industrial enclosures in commercial security installations
• Single-unit package provides consistent penetration sizing across multi-enclosure deployments — standardize on one port diameter for all main panel and equipment cabinet entries

The DAP4BC-G0-4 solves the cable-entry problem that kills UL ratings and creates service headaches: knockout holes leave sharp edges that abrade cable jackets, conduit fittings add bulk and limit cable count, and rubber grommets degrade under UV exposure or temperature cycling. This port installs into a standard 4-inch chassis punch and provides a smooth, rounded entry surface that won't damage cable jackets during pulls. The brushed cable-pass-through design allows cables to move slightly during service (when you're swapping a camera or adding a new sensor run) without breaking the environmental seal or requiring disassembly. For outdoor security system main panels and rooftop equipment enclosures, the UL50E rating ensures the port withstands rain intrusion, ice formation, and windblown dust without compromising the enclosure's NEMA 3R or 4X rating. In industrial environments — manufacturing facilities, warehouses, food processing plants — UL508A compliance means the port meets requirements for control cabinets housing access control panels, PoE midspan injectors, and 12/24VDC power distribution.

The 4-inch diameter is sized for mid-density cable runs typical in commercial security and access control installations. A single port handles eight Cat6 cables (for four 2-door access control zones or eight IP camera drops), four 18/2 power pairs (for door strikes and REX sensors), and two RG59 coax runs (for analog PTZ RS-485 control) with room for service slack. For higher-density applications — central equipment rooms with 20+ camera home-runs or industrial control cabinets with PLC I/O bundles — multiple ports can be installed in a vertical column to separate cable groups by function (network on top, power in middle, low-voltage control at bottom). The brushed pass-through accommodates both round and flat cable bundles; you're not limited to perfectly circular cross-sections, so you can route a mix of Cat6, MC cable, and flexible conduit through the same opening. During installation, the port installs from the exterior side of the enclosure with a snap-in or screw-mount attachment (confirm model-specific mounting per Panduit's installation guide), and cables feed through before you make terminations — no need to disconnect terminated cables to service the enclosure later.

This port is CSA-certified to C22.2 NO. 14-13 (industrial control equipment) and NO. 94.1/94.2 (enclosed and dead-front switches), making it compliant for Canadian installations where provincial electrical codes require CSA marks on all enclosure components. For integrators working cross-border projects or supplying equipment to Canadian facilities, the dual UL/CSA listing eliminates the need to source separate components for U.S. and Canadian sites. Single-unit packaging (one port per package) allows you to order exact quantities for project needs without overstocking; for large deployments, order in multiples of your per-enclosure port count (e.g., two ports per main panel × 12 buildings = 24-unit order). When specifying this port, confirm your chassis punch size matches the 4-inch requirement, verify your cable bundle diameter stays under 3.5 inches effective (measure the bundle with cables loosely grouped, not compressed), and ensure your enclosure's UL rating includes compatibility with field-installed cable entry devices — most UL50-listed enclosures explicitly allow UL-listed cable entry products, but double-check the enclosure's installation instructions or UL file for any restrictions on field modifications.
