Two hour concrete floor Penetration for a 3'6 inches x1'8 inches
At Huntington Pasadena Hospital, we have a project that requires a duct to start at ground level and penetrate
through 7 floors vertically without a fire damper. We need a 2-hour rated assembly to install around the duct at each floor
