With the use of roof supports, it is possible to damage-free the introduction of insulated wires that provide the electricity supply of buildings from the 230/400 V low-voltage overhead power distribution network into the so-called into roof support steel pipes. The inlet also ensures that precipitation (rain, snow) cannot enter the steel pipe.
The inlet is made for 1.5", 2" and 2.5" steel pipes. The lower part of the two-part plastic inlet, with a conical design, is tightened into the steel pipe of the appropriate size without any additional fastening device, and the upper part can be attached to the lower part with screws after the wires have been placed and introduced.
