This professional-grade slotted duct PVC cable trunking (often called wiring duct or finger duct) measures 40mm in height by 25mm in width and comes in standard 2 meter rigid lengths. Finished in a distinct industrial blue, this slotted open-finger management channel is specifically engineered for organizing, routing, and protecting control wiring within electrical switchboards, industrial automation panels, and server enclosures.

Specification

• Model Dimension: H40W25 (40mm Height x 25mm Width)
• Length: 2 Meters
• Material: High-Impact, Flame-Retardant PVC (Polyvinyl Chloride)
• Slot Configuration: Open-slot design with breakout fingers
• Color: Industrial Blue (Often used to designate intrinsically safe wiring paths or standard automation control loops)
• Flammability Rating: Self-extinguishing; UL94 V-0 compliant
• Operating Temperature Range: -5℃ to +60℃ 
• Mounting: Pre-punched base mounting slots for easy screw/rivet attachment

Features

• Breakout Fingers and Open Slots: Parallel slots along the sidewalls allow wires to be routed out at any specific height along the run. The individual PVC fingers feature integrated scorelines at their base, allowing quick, toolless snapping to create wider openings for heavy wire bundles.
• Non-Slip Snap-On Cover: The trunking includes a matching rigid cover with a robust interlocking design. It easily snaps into place and resists sliding or popping off, even when the duct is packed to capacity or mounted upside down.
• Intrinsically Safe Signaling Color: The blue color scheme is universally recognized in industrial environments to isolate and identify specific circuitry, such as lower-voltage control loops or intrinsically safe wiring segments.
• Dielectric Safety & Flame Retardancy: Constructed from premium electrical-grade PVC that provides excellent insulation properties, eliminates grounding issues, and self-extinguishes rapidly in case of an electrical fault or flashover.

Common Applications

• Industrial Control Panels & PLCs: Managing complex wiring arrays linking Programmable Logic Controllers (PLCs), relays, contactors, and terminal blocks.
• Electrical Switchboards & Distribution Boards: Organizing power and control lines inside main electrical panels to keep high and low-voltage paths cleanly separated.
• Server Racks & Network Enclosures: Vertical or horizontal data cable routing within telecom racks where cords must exit at precise rack unit (RU) intervals.
• Machine Tool Automation: Routing sensory feedback and power cables along automated factory floor machinery.

Professional Usage & Deployment Tips

• Calculate the 60% Fill Capacity: To maintain proper heat dissipation and prevent wire pinching, do not pack the trunking completely solid. Calculate your total wire cross-sections to fill no more than 40-60% of the duct's interior area.
• Clean Cuts for Flush Corners: When creating right-angle (90℃) turns or T-junctions, use a dedicated trunking cutter or a fine-toothed hacksaw. Miter-cutting the base and cover at a 45℃ angle ensures a seamless, professional finish without sharp gaps.
• Smooth Edges After Breakouts: If you use pliers or a utility knife to cut away a section of the base spine for a wide cable bundle, ensure you smooth down any rough plastic edges. Sharp PVC burrs can scrape or cut into wire insulation over time due to machine vibration.
• Stagger Base and Cover Joints: When mounting multiple 2 meter sections consecutively over long spans, stagger the joints of the base channels and the top lids. Offsetting the cover breaks by at least a few inches significantly reinforces the structural rigidity of the overall assembly.
