Cable duct Legrand Koryto KABLOWE PROSTE LE-638120 20x12 mm

Legrand Koryto KABLOWE PROSTE LE-638120 20x12 mm is a straight cable duct for routing and protecting electrical and low-voltage cables. With internal dimensions of 20 x 12 mm, this profile is intended for small cable runs where space is limited, offering a compact solution for tidy wiring under skirting boards, along walls or in light commercial installations. The duct is designed to provide mechanical protection and help maintain an organized cable layout while contributing to a neat finished appearance.

Advantages

The product delivers consistent cable guidance and separation in confined spaces without requiring invasive installation work. Its straight profile enables simple cutting and joining on site, while the smooth inner surface reduces stress on cable sheaths. The duct supports visible and concealed installations and facilitates later access to cables for maintenance or changes.

Suitable for

• Routing electrical and low-voltage cables in residential interiors
• Small office or retail installations with limited space
• Neat surface wiring along skirting boards and walls
• Temporary or permanent cable runs requiring mechanical protection

Key specifications

• Internal dimensions: 20 x 12 mm
• Profile type: straight cable duct
• Application: routing and protection of electrical and low-voltage cables
• Installation: surface mounting under skirting or along walls
• Finish: smooth inner surface for reduced cable wear

How to use

Measure the required length along the intended route and cut the duct to size using an appropriate saw or cutter. Prepare the mounting surface to ensure it is clean and dry, then attach the duct using suitable screws or adhesive recommended for the wall finish. Route the cables inside the duct, avoiding sharp bends beyond the cable manufacturer’s minimum bend radius, and close or cap the duct ends as needed for a neat finish. For multi-segment runs, join sections securely and check that covers are properly seated.

Usage recommendations

Select fixing materials compatible with the mounting surface and choose cable entries that avoid compression of cable sheaths. For installations carrying data or sensitive signals, keep power and signal cables separated where possible. Regularly inspect accessible runs to ensure clips or adhesives remain secure and to verify there is no damage to the duct or contained cables.
