CFU honeycomb strain relief: strain relief within seconds

Installation note: 80% faster (compared to CFX strain relief) for different cable types in different chambers, fully flexible, with strong holding strength and easy assembly.


When used in e-chains, the CFU honeycomb strain relief saves time, increases flexibility and reduces material wear thanks to its tribologically optimised clamping strength. Different cables can be strain-relieved without problems in one layer.
Harnessing is simple, fast and flexible, cables can now be replaced easily. Due to the special structure, cables with diameters between 2 and 17mm can be fixed quickly.

  • 80% faster filling compared to igus® CFX clamps
  • Universal applications
  • Flexible layout

Honeycomb strain relief CFU  
Product feature:

  • The CFU honeycomb strain relief is openable on both sides
  • Strain relief can be screwed in from above or below
  • Enables strain relief of different cables in one chamber
  • Structurally stable, black anodised aluminium rails
  • Compact design, which is smaller than the mounting bracket of the e-chain at the upper end, meaning it can also be used for long travels

Honeycomb strain relief CFU  
All the advantages at a glance:

  • Optimised surfaces of plastic honeycomb for a strong force fit and for higher holding force of the cables.
  • New side sections for assembly and disassembly in seconds
  • Strain relief for different cables in one layer
  • Simplified parts
  • Ideal for short unsupported applications
  • Can be used at the fixed end for gliding applications as the upper edge of the CFU is lower than the chain surface
  • Can be used at the fixed end in the guide trough
