Spiral conduit tube KRK-25P/25M, flexible spiral ducting, 25 mm diameter, 25 m roll

Spiral conduit tube KRK-25P/25M is a flexible spiral ducting supplied as a 25 m roll with a nominal 25 mm internal diameter. It is designed for routing and protecting electrical and low-voltage cables in residential and light commercial installations. The spiral construction allows bending around corners and obstacles while maintaining cable organization and mechanical protection. The roll format lets installers cut custom lengths to match site requirements and minimize waste.

Advantages

The flexible spiral design provides good bendability and impact resistance while keeping cables neatly bundled and protected from abrasion. Supplied as a 25 m roll, the tubing is convenient for continuous runs and reduces the number of joints. The 25 mm internal diameter accommodates multiple conductors, cable assemblies or small cable bundles typical in power, data and control wiring. Installation is simple with standard cutting tools and common cable insertion methods.

Suitable for

• Routing and protecting electrical cables in homes and apartments
• Organizing low-voltage wiring for data, audio and security systems
• Flexible connections in light commercial or office installations
• Protecting cable runs through ceilings, walls and service compartments

Key specifications

• Nominal internal diameter: 25 mm
• Length per roll: 25 m
• Construction: flexible spiral ducting
• Material: durable polymer suitable for mechanical protection (non-metallic)
• Bendability: suitable for curved and routed runs without kinking

How to use

Measure the required run and cut the spiral conduit to length with appropriate cutting tools. Insert cables either before or after fixing the conduit in place depending on access and accessibility. Secure the conduit with clips or ties at regular intervals to prevent sagging and to maintain alignment with mounting surfaces. Use appropriate grommets or bushings when passing the conduit through sharp-edged openings or panels to avoid abrasion of the cable sheath.

Usage recommendations

For best results, avoid overfilling the conduit—leave enough space for cable movement and heat dissipation. When routing power and signal cables together, follow local electrical codes regarding separation and grouping. Store the roll flat and protected from prolonged UV exposure to maintain flexibility and material properties.
