Proven durability & stability for large cable carriers

The E4-1 system combines all the benefits of its three predecessors in the E4 range. E4-1 cable carriers offer greater stability with the same or smaller dimensions while almost all the accessories and mounting brackets are the same. With igus® E4-1 cable carriers, the service life of your application can be increased and costs significantly reduced.  If you'd like to request a free sample sleeve, simply fill out the form here.
