The window cleaners were stuck at the Hearst building in Manhattan on Wednesday afternoon.
Fire department officials say other workers cut open windows on the 44th floor and pulled the men inside.
The metal scaffold appeared to have buckled in the middle. The men were on either side, communicating with firefighters on the roof of the 46-story building for about an hour and a half before they were rescued.
The Hearst Tower is the world headquarters of the Hearst Corporation.
