Sept 21 (Reuters) - Wall Street's main indexes slipped at the open on Monday as concerns about fresh coronavirus-driven lockdowns and the inability of Congress to agree on more fiscal stimulus raised fears about another hit to the domestic economy.

The Dow Jones Industrial Average hit a near two-month low shortly after opening 172.71 points, or 0.62%, lower at 27,484.71.

The S&P 500 opened lower by 33.90 points, or 1.02%, at 3,285.57 and the Nasdaq Composite dropped 183.14 points, or 1.70%, to 10,610.14 at the opening bell. (Reporting by Devik Jain in Bengaluru; Editing by Anil D'Silva)
