During heavy rain or melting snow, if the water is not diverted properly it can flood basements, manholes, subways, etc. Storm water flows into the storm system through inlets, catch basins, or a combination of two. An inlet is a hole in the street or curb. A catch basin is a rectangular storage tank located under the street. Both of these are covered by an open, cast iron grate or cast iron round inlet cover.


We have a number of different configurations of cast iron frames and grates and inlet covers to which we have been adding new configurations and sizes continuously. If you don’t find what you are looking for, let us know. We will be happy to develop frames and covers per your requirements and supply the sample for your approval before the shipment.
