Iron cover for utility duct: Iron cover for pedestrian-vehicle boundary Product name: EV600×1200×H250 By allowing the receiving frame to slip under the L-shaped gutter, it is possible to reduce the relocation of existing buried pipes. - When installing a special section near the pedestrian-vehicle boundary, the installation position of the iron cover and the special section can be moved approximately 100 mm closer to the roadway compared to conventional iron covers. - This expands the possibility of avoiding the relocation of existing underground piping. - Inspection openings can be installed within the sidewalk even in areas where the sidewalk width is narrow. *This helps avoid road restrictions during inspection work by utility managers and ensures the safety of the work.
