Overview

The nVent F66T160GVWK Straight Section Lay-in Flat Cover Type 1 is a premium galvanized steel wireway component designed for safe, efficient, and code-compliant cable management in commercial, industrial, and institutional facilities. This 60-inch straight section features a fully open side for effortless wire and cable installation, eliminating the need for labor-intensive pull-through methods that risk insulation damage. The flat cover design enables flush mounting to walls or ceilings, ensuring a clean, professional appearance while providing easy access for maintenance and future modifications via keyhole screw slots. Constructed from high-quality galvanized steel, this Type 1 wireway section delivers superior corrosion resistance, making it ideal for both indoor and outdoor applications in harsh environments such as manufacturing plants, data centers, healthcare facilities, and utility installations. Engineered for durability and versatility, the F66T160GVWK accommodates a wide range of wireway configurations with its 6x6x6 knockouts (KOs), allowing for seamless integration with bends, tees, and other fittings. The Type 1 designation ensures compliance with NEC (National Electrical Code) requirements for non-metallic sheathed cable (NM), service entrance cable (SE), and underground feeder cable (UF), providing peace of mind for electrical contractors and facility managers. Available in lengths from 12 inches to 120 inches, this straight section can be customized to meet the specific demands of any project, whether it’s a new construction installation or a retrofit upgrade. Installation is simplified with the open-side design, enabling wires to be laid in directly without the need for threading through tight spaces—a critical advantage in retrofit scenarios where existing infrastructure limits accessibility. The galvanized finish not only enhances corrosion resistance but also provides a consistent, professional appearance that blends seamlessly with other electrical enclosures. nVent, a trusted leader in electrical and thermal management solutions, backs this product with decades of engineering expertise, ensuring reliability, safety, and long-term performance. Typical applications for the F66T160GVWK include: - Commercial buildings: Office complexes, retail spaces, and hospitality facilities requiring organized, code-compliant cable management. - Industrial facilities: Manufacturing plants, warehouses, and processing centers where robust wireway systems are essential for power distribution and control wiring. - Institutional settings: Schools, hospitals, and government buildings where safety, accessibility, and compliance are paramount. - Outdoor installations: Utility enclosures, solar farms, and telecom sites where environmental durability is critical. Professionals select nVent wireway systems for their unmatched combination of strength, flexibility, and ease of installation. The Type 1 flat cover design ensures quick access for inspections or modifications, while the galvanized steel construction guarantees longevity even in corrosive or high-moisture environments. Whether used in new construction or as part of a system upgrade, the F66T160GVWK delivers the performance and reliability that electrical contractors and facility managers demand.
