Corrugated conduits

When choosing corrugated cable conduit, specify the route, clear internal size required and installation conditions. Compare specific series and references, checking the conduit together with its accessories.

From cable dimensions to conduit dimensions

Prepare a list of cables for the relevant section and their external dimensions. Then check the chosen conduit's internal diameter and project requirements. Do not treat an external designation as a clear internal opening. Product titles include separate external and internal size designations; use these for initial comparison and confirm exact values in the reference's documentation. For tight passages, also check the overall dimensions of the complete connection.

Check route conditions by series

The category contains titles with different material designations, colours and versions. Clarify where the conduit will run and which influences matter there. Then seek confirmed characteristics for the chosen series. Do not infer sunlight resistance, mechanical load resistance or other conditions solely from colour and general name. If the project requires a specific classification, check it for the exact code, including applicable manufacturer limitations.

Accessories are part of the choice

Check the couplings, clips, caps and transitions required in conduit accessories. Compare the system and connection, rather than nominal size alone. Clarify whether the chosen conduit is described with a draw cord and what the package includes; do not assume identical versions for every item. In a prepared list, record the corresponding accessory immediately beside the conduit with which it will be used.

When to consider another format

If the route solution is not yet specified, also compare the task with rigid conduits. Choosing between formats follows installation conditions and requirements for the specific route. The general cable conduits section helps organise sections and accessories. To compare within a brand presented, continue to KOUVIDIS or LEGRAND, checking each series using its own data. Before ordering, compare the length required with the unit and package described.
