Overview

The nVent **F66T172GV 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 applications. Engineered for durability and ease of installation, this 72-inch straight section provides a robust solution for enclosing and protecting electrical wiring in wireway runs while eliminating the need for labor-intensive wire pulling. Unlike traditional conduit systems, the lay-in flat-cover design allows technicians to simply place wires and cables into the open section, reducing the risk of insulation damage and speeding up installation workflows. This approach is particularly valuable in retrofit projects, data centers, manufacturing facilities, and large-scale electrical installations where minimizing downtime is critical. Key features of the nVent F66T172GV include a **completely open one-side design**, enabling quick and hassle-free wire placement without the need for threading cables through tight spaces—a common source of insulation damage in pull-through wiring systems. The **Type 1 flat cover** ensures a flush mount to walls or ceilings, providing a clean, professional finish that meets NEC and OSHA safety standards. The **galvanized steel construction** delivers superior corrosion resistance, making it ideal for both indoor and outdoor applications, including harsh environments such as chemical plants, water treatment facilities, and coastal installations where moisture and corrosive elements are prevalent. Available in lengths from 12 inches to 120 inches with or without knockouts, the F66T172GV offers unmatched flexibility for custom wireway layouts. The **keyhole screw slots** on the flat cover simplify access for future modifications, inspections, or additions, ensuring long-term adaptability as system requirements evolve. This product is part of nVent’s trusted CADDY® line of cable management solutions, a brand synonymous with innovation and reliability in the electrical industry. With a **US-made** pedigree, the F66T172GV meets stringent quality standards and is backed by nVent’s global reputation for engineering excellence. Professionals in the electrical contracting, industrial maintenance, and building automation sectors rely on nVent wireway systems for their **durability, compliance, and ease of use**. Whether used in new construction, renovations, or critical infrastructure projects, this straight section ensures reliable cable protection while streamlining installation. The absence of knockouts in this specific model (Type 1 no KOs) makes it particularly suitable for applications where custom routing or additional openings are not required, reducing the risk of accidental damage during installation. For projects demanding high-performance cable management with minimal disruption, the nVent F66T172GV stands as a proven choice.
