## Summary description

Onnline RL-18B is a 3-meter electrical installation conduit with an 18 mm internal diameter in white finish. Designed to protect and route electrical cables and wiring in residential and light commercial installations, it provides a rigid channel for organizing conductors, reducing mechanical damage and simplifying cable runs through walls, ceilings and service areas.

## Long description

Onnline RL-18B is a rigid electrical installation conduit with an 18 mm internal diameter and a length of 3 meters in white finish. It is designed to protect and route electrical cables and wiring in residential and light commercial settings. The conduit creates a fixed pathway for conductors, reducing the risk of mechanical damage, simplifying cable routing through walls, ceilings and service areas, and helping to maintain a neat installation.
Advantages
The conduit is made to provide mechanical protection and to keep cables organized over long runs. Its 18 mm internal diameter accommodates common power and signal cables used in domestic and small commercial installations. The white finish integrates visually with typical interiors and ceilings, while the rigid construction ensures a stable and durable channel for wiring. Its 3 m length reduces the number of joints required on longer runs, which can simplify installation and improve the continuity of protection.
Suitable for
Routing power cables and low-voltage wiring in residential apartments and houses
Organizing wiring in light commercial premises, offices and retail spaces
Protecting cables in ceiling voids, under skirting or inside service ducts
Use in renovation projects where surface-mounted conduit runs are needed
Key specifications
Internal diameter: 18 mm
Length: 3 m per piece
Color/finish: white
Type: rigid electrical conduit for cable protection and routing
How to use
Measure the required conduit run and cut the conduit to the needed length using an appropriate saw or cutter for plastic. Deburr cut edges to avoid sharp edges that could damage cable insulation. Fix the conduit to surfaces with suitable clamps or brackets at recommended intervals and use appropriate fittings, bends and connectors to change direction or join sections. Pull cables through the conduit using fish tape or a pull line; ensure cables are not excessively bent and comply with local installation regulations and cable fill recommendations.
Usage recommendations
For best results, plan the cable route before installation to minimize joints and bends. Use matching fittings and secure mounting hardware rated for the conduit diameter. Check compatibility with the cable types and quantities to avoid overcrowding and follow applicable electrical codes for safe and compliant installation.
