Outdoor cable ducts allow you to distribute electrical cables along walls without demolition. The choice depends on the environment: use PVC or metal models, skirting board versions for living spaces, and IP55 waterproof rigid pipes for outdoors, ensuring safety and mechanical protection.

Tools and Components Required for Installation

Before starting, gather essential tools: measuring tape, spirit level, pencil, hacksaw or PVC cutter, screwdriver, drill with masonry bits, wall plugs, screws, and a wire stripper. For outdoor installations, consider outdoor lighting accessories and outdoor decor to integrate ducts seamlessly.

Expert Tips

  • Always use IP55-rated ducts for exposed outdoor areas to prevent moisture ingress.
  • Plan cable routes to minimize bends, as sharp turns can damage wiring.
  • Secure ducts with brackets every 50 cm for stability.

Cuts and Dimensions

Measure the wall length precisely and mark cut points on the duct. Use a fine-tooth saw for clean edges. For corners, miter cuts at 45 degrees ensure a professional finish. Check our wall decor collection for covers that hide unsightly transitions.

Junctions of Outdoor Cable Ducts

Junctions connect duct sections or change direction. Use L-shaped or T-shaped connectors for right angles, and flexible sections for slight curves. Seal joints with silicone for outdoor use to maintain IP55 integrity. Pair with lighting fixtures that match your duct layout.

Installing Skirting Board Cable Ducts

Skirting board ducts replace existing baseboards. Remove old skirting, cut the duct to length, and fix it to the wall with adhesive or screws. Feed cables through compartments and snap on the cover. This method works well in living rooms near sofas or TV entertainment furniture.

Wall Mounting of Ducts and Electrical Boxes

For wall-mounted ducts, drill holes at marked intervals, insert wall plugs, and screw the duct base in place. Attach electrical boxes at connection points using compatible brackets. Ensure boxes are level and sealed. Browse desks and work surfaces for organizing home office cable runs.
