Cable trays are intended for the construction of cable paths with surface cable laying. Cable trays allow you to lay your cables effectively along the desired routes. Cable tray systems enable an easy, fast and efficient installation. The mounting solutions provide an easy and fast joining of cable trays as well as suitable galvanic connections, whereas the connection between the trays does not damage the cables. Such a quality connection is possible without an additional connecting elements. The construction is therefore not only better and faster, but also more economical. The edges of the trays are curved in a way that reduces the possibility of damage during installation to a minimum.
