Abstract: A catch basin curb inlet opening cover is a steel plate member which includes a main segment having at least one first opening whereby fluid may pass through said at least one first opening into the curb inlet opening when said plate member is positioned in its intended place, and a bend portion. The bend portion is formed from the main segment by deforming a respective section of the main segment. When in place across the curb inlet opening, the bend portion extends into the curb inlet opening. A respective surface of the bend portion is in sufficiently close proximity to either or both of the left edge or the right edge of the curb inlet opening so that the plate member will resist horizontal movement occasioned by being struck by a snow plow or other heavy duty street equipment. Adjusting means are described which adjust the length of the bend portion to accommodate different inlet openings. The main segment includes a further opening adapted to permit the viewing of a precautionary badge.
