Wiring duct including top section and bottom perforation for horizontal and vertical laying of electrical cables and lines in the control cabinet. Designed as a metric duct. The nominal size of the system corresponds to the inside size of the ducts. The webs can be broken out without tools. Flush with the floor is possible thanks to predetermined breaking points. Tapering in the side slots prevents the cables from falling out. Tested according to DIN EN 50085-2-3. Special lengths on request.
