Cable clamp Rittal 7979.020, plastic, black, pack of 20

Rittal 7979.020 is a pack of 20 black plastic cable clamps designed for securing and organising cables inside electrical enclosures, control cabinets and other industrial installations. Manufactured from durable plastic, these clamps provide simple attachment and reliable routing for individual cables or small cable bundles, helping to maintain tidy cable runs in servers, PDUs and similar equipment.

Advantages

These cable clamps are supplied in a pack of 20 and are made from resilient plastic that resists common wear in indoor electrical environments. Their compact, low-profile design allows straightforward mounting and retention of cables without requiring specialised tools. The black finish provides a neutral appearance that blends with most enclosures and equipment.

Suitable for

• Securing single cables or small bundles inside control cabinets
• Organising cable runs in server racks and PDU compartments
• Routing signal and power cables in industrial enclosures
• Applications where a simple, non-metallic clamp is preferred

When it may not be suitable

These plastic clamps are intended for indoor electrical enclosures and are not specified for direct outdoor exposure, prolonged UV radiation or harsh chemical environments. They are not intended as a primary mechanical strain-relief for heavy or high-tension cable runs where metal clamps or specialised strain-relief fittings are required.

Key specifications

• Quantity: 20 pieces per pack
• Material: plastic
• Colour: black
• Application: cable securing and routing inside enclosures and equipment

How to use

Install the clamp at the desired mounting point within the enclosure, position the cable or small bundle into the clamp slot and engage the clamp to retain the cable. These clamps are designed for straightforward attachment and removal, allowing reconfiguration of cable runs during maintenance. Ensure cables are routed without sharp bends and that the clamp retains the cable without excessive compression.

What to consider before purchase

• Verify that a pack of 20 meets the quantity required for your installation
• Confirm that plastic material and black colour suit your environmental and aesthetic needs
• Check cable diameters to ensure proper fit in the clamp profile
• Consider using metal or specialised strain-relief fittings for heavy or high-stress cables

Usage recommendations

Use these Rittal cable clamps for tidy internal cable management in control cabinets, server racks and PDUs. Avoid exposure to direct outdoor weathering and select alternative fittings where mechanical strain-relief or UV resistance is required.
