Cable protection sleeve self-closing double-layer 5 m x 10 mm DELOCK 19020

DELOCK Cable protection sleeve self-closing double-layer 5 m x 10 mm is a flexible, reusable sleeve designed to bundle and protect cables from abrasion, kinking and tangling. The 5-metre length and 10 mm diameter suit routing and organisation of small cable bundles in offices, home entertainment setups, server racks and vehicle installations. The self-closing construction allows insertion and removal of cables without tools while a double-layer build increases stability and protection for wiring.

Advantages

The double-layer construction provides increased mechanical resistance while maintaining flexibility for easy routing. A visible wear indicator helps detect heavy wear early: when the inner orange layer becomes visible, the sleeve should be inspected and replaced if necessary to protect the enclosed cables. The sleeve is reusable, made from polyester monofilament and multifilament, and rated to UL 94 for flammability. It also withstands a wide temperature range for varied installation environments.

Suitable for

• Bundling and protecting power and data cables behind desks and entertainment centres
• Cable management in server racks and network cabinets
• Use in vehicles to protect wiring looms from abrasion and wear
• Industrial or workshop applications where flexible, abrasion-resistant protection is needed

When it may not be suitable

This sleeve is intended for small cable bundles and has a 10 mm diameter; it may not be suitable for large cable harnesses or very thick single cables. It is not a sealed conduit and does not provide liquid-tight protection or high-voltage insulation by itself.

Key specifications

• Length: 5 m
• Nominal diameter: 10 mm
• Construction: self-closing, double-layer sleeve
• Material: polyester monofilament and multifilament
• Reusable design
• Wear indicator: inner coloured layer visible on abrasion
• Temperature range: -40 °C to 150 °C
• Flammability classification: UL 94

How to use

Cut the sleeve to the required length and open the self-closing channel to insert cables. Position the sleeve around the cables and allow it to close around the bundle; no tools are required. For routing through tight spaces, compress the sleeve slightly and guide the bundle through openings. Regularly inspect the sleeve and the wear indicator: if the inner orange layer becomes visible, remove and replace the sleeve to avoid exposing cables to abrasion.

What to consider before purchase

• Check that the 10 mm diameter is sufficient for your cable bundle or if a larger sleeve is needed
• Ensure the 5 m length matches your routing requirements or plan for multiple pieces
• Confirm that the sleeve’s non-sealed design meets your environmental protection needs (not liquid-tight)
• Verify temperature range and flammability class are suitable for the installation environment

Recommendations

For neat cable management, group similar cables (power, data) separately and avoid overfilling the sleeve. Monitor the wear indicator periodically in high-friction installations and replace the sleeve when the inner coloured layer appears to maintain protection and safety.
