A catch basin insert or filter is supported in an open type curb inlet storm drain found on streets and in parking lots. Catch basin filters and inserts are designed to collect coarse sediments, oil, grease and debris from storm water runoff. Such filters normally require support on all four sides of a grate using the weight of the grate. A loop and rod attaches one or more sides of a filter or insert inside a curb inlet storm sewer vault instead of using the weight of the grate.
