General Information

HASSCO’s ULC approved steel retrofit overfill boxes are designed to thread into an existing fill opening of a tank that does not currently meet overfill requirements. These boxes are intended to capture small amounts (up to 15L) of product during normal filling procedures. HASSCO’s overfill box is equipped with a lockable, hinged cover to prevent debris from entering the filling area.
