Corrugated slotted protection hose NW 37 for cable routing and rodent protection Length 25 m | Outer diameter AD 42 mm | Inner diameter ID 36.7 mm What this product does Flexible corrugated tube with longitudinal slot for quick, tool insertion of cables. Designed as an empty protection pipe for electrical, telecom, and control cables where a continuous, accessible conduit is needed. Nominal width NW 37 and precise dimensions allow predictable fit with junctions, connectors, and standard installation accessories. Key benefits Easy installation: the slotted, open design lets you add or remove cables without disconnecting runs or cutting the tube. Spaceefficient protection: AD 42 mm outer diameter and ID 36.7 mm inner diameter provide ample space for cable bundles while keeping the profile compact. Long continuous length: 25 m roll minimizes joints and reduces installation time on long runs. Robust corrugated construction: maintains flexibility for routing around bends while providing structural support along the run. Compatible with common conduit fittings sized for NW 37 and 42 mm outer diameter, helping integrate with existing systems. Features and specifications Product type: corrugated slotted protection pipe, open hose, empty tube Nominal width: NW 37 Outer diameter: AD 42 mm Inner diameter: ID 36.7 mm Length: 25 m Use: cable protection and guided routing in building installations, industrial equipment, and outdoor runs Practical use scenarios 1) Building renovation: Run data and power cables along ceilings and walls without tearing open finishes. The slotted tube lets you feed additional cables later without opening installed runs. 2) Outdoor lighting and garden installations: Create a continuous conduit for lighting and lowvoltage control cables where a weatherproof trench or surface run is required. The corrugated design eases routing around obstacles. 3) Machinery and vehicle wiring looms: Provide a flexible protective channel for control cables in workshops or service vehicles where frequent access or cable changes are expected. Installation tips Use compatible clamps, grommets, and end caps designed for AD 42 mm or NW 37 to secure the run and seal entry points. For multiple bends, support the tube at regular intervals to avoid sagging and to maintain cable pathway integrity. For retrofit work, open the slot, position the cable, then snap the tube into place and secure with ties or clamps as needed. This corrugated slotted hose provides a practical, readytoinstall solution for organized, accessible cable protection and routing in a wide range of installation environments.
