Dimensions Dimensions

The maximum cable diameter strongly depends on the bending radius and the desired cable type. Please contact us.
For rough environmental conditions, we recommend the use of OFFROAD glide shoes with 80 % higher wear volume.

Divider systems

As a standard, the divider system is mounted on each crossbar – for stay mounting on every 2nd chain link (HS). As a standard, dividers and the complete divider system (dividers with height separations) can be moved in the cross section (version A). 

The dividers are easily attached to the stay for applications with lateral acceleration and for applications laying on their side by simply turning the frame stay by 180°. The arresting cams click into place in the locking grids in the crossbars (version B). The groove in the frame stay faces outwards.

When using plastic partitions with ax > 112 mm, we recommend an additional center support with a twin divider (ST = 4 mm). Twin dividers are also suitable for retrofitting in the partition system.
