DISCONTINUED MODEL For new constructions, we recommend the technically improved e-chain® Series 14340 from the igus® E4/light product range.+25% more unsupported length, higher stability and tensile strength, same dimensions and connection dimensions Series 143 is available from stock in limited numbers. Product support and storage are limited as of 2012. For questions, please refer to your igus® contact person. Thank you for your understanding to the E4/light Series 14340
* The required clearance height is HF = H + 50 mm (at 2 kg/m fill weight), which should be observed in all types of applications. Please contact us if you have particularly confined space requirements.
** The calculated length corresponds to the chain length without mounting brackets.

Other installation types
Separators can be arranged in any position in the chain cross-section. The standard separator part no. 407 offers secure standing ability through its wide base, even for large cables/hoses. All separators can be moved and can be fixed can be fixed in position by spacers for side-mounted applications. Note: The available inner height is reduced by 2 mm for each spacer, which can reach 4 mm with spacers attached on both sides. To prevent this, parts can also be installed from the outside onto the opening crossbar.
With the various elements of the interior separation, the e-chains® can be divided both vertically and horizontally. Side plates and shelves allow a flexible separation structure. Shelves of various widths can be arranged in steps of 7mm on 7 levels. You can find recommendations for assignment in the "Design" chapter.

"Super-aluminium" trough - the igus® standard for guide troughs
The "Super-aluminium" trough is a modular system of guide troughs for long travels (where e-chains® glide on each other). The basic "Super-aluminium" trough is available in simple, cost-effective "basic designs" and can be expanded for sophisticated plant construction. This universal usability makes it the recommended igus® standard for guide troughs.
