Installation may be made with building into the wall or concrete by conventional technology and may be installed exposed as well. Tubes are applicable in dry, dusty, contaminated or periodically humid, hazy, vaporous or corrosive vaporous rooms having “C” and “D” classification for inflammable risk (between temperature range of (-5) °C and (+60) °C. It protects cables and tubes on the medium level of mechanical employment. The type of protection will be specified by the properties of pipe network and its accessories and the development of connections. Material: Rigid PVC for electrical use

Colour: grey or brown
