Separators can be positioned at any point in the tube cross-section. The standard separator part no. 381 acts as a secure support by virtue of its wide base, even in the case of thick and cables/hoses
The separator 381T is intended for energy tubes to be equipped with several separators. This separator engages very firmly on the floor of the energy tube, and very loosely in the lid. This allows easy opening of the lid. Ensure that the separators are identically aligned in this case. The injected article number serves as orientation here.
Additionally available for applications with energy tubes available: Locking separator part no. 384

The various elements of the interior separation kit allow vertical as well as horizontal division of the Energy Chains® and tubes Side-plates and shelves form the basic framework of a rack system. On a height grid of 0.28 (7 mm), shelves of different widths can be arranged in 5 stages. Assignments are recommended in the chapter titled "Design specifications".
During installation of the "open" slotted separator, the uppermost and lowermost "grid levels" cannot be occupied by a shelf.
Examples of interior separation:
Slotted separators Art. No. 391 for very fine divisions. However, these separators cannot be integrated into an existing system of divisions without prior dismantling of the interior separation. Slotted separator Art. No. 397 which is open on one side can be post-integrated into existing interior-separation systems without the need for dismantling them beforehand (Does not apply to shelves at the uppermost or lowermost levels).

Aluminum "Super Trough"- the igus® standard

The Aluminum "SuperTrough" is a modular guide trough system for long travels (when E-Chains® glide on themselves, as per sketch). Aluminum "SuperTrough" is available in low cost "basic versions" and can be upgraded for heavy duty applications. This universal usage makes it the igus® recommended new standard trough system.

Multiple fastening options with heavy duty brackets, bottom clamps and interface connectors
Side-mount glide strips for wear protection in high-speed
Corrosion proof through seawater resistant aluminium
Flexible assembly - connects with underground, independent from profile length and location of trough section interfaces

Guide troughs are used for applications in which the upper run of the Energy Chain® glides on the lower run. The following components are required if the igus® steel guide trough is used.Guide trough without glide bars part no. 93-30, guide trough with glide bars part no. 93-31. Installation sets as a joint connection part no. 93-50. XX
.XX indicates the length of the C-profiles on which the guide trough is mounted.The standard length of the trough components and glide bars is 6.56 ft (2 m). The required total length of the guide trough is determined by the travel.
