2 Correct use
The screw-on cable tray systems are used to support and route all kinds
of cables, taking the approved load values into account. Depending on
the corrosion protection used, they can be mounted both indoors and
outdoors.
The cable tray systems are suitable for use at ambient temperatures
of ‒20 °C to +120 °C. At temperatures below ‒20 °C, the material will
become brittle and may not be processed further.
The screw-on cable tray systems are not designed for any other purpose
than the one described here. If the screw-on cable tray systems are used
for another purpose, any liability, warranty or damage claims shall be
rendered null and void.
