Multiple Section Structural Support
For multiple section wide and single section high louver installation, review Tables to determine if an
additional structural support will be required based on the louver section width and height of the louvers
being installed. If additional support is not required, reference the Multiple Section Wide and Single Section
High-Unsupported installation instructions. If additional support is required, reference the Multiple Section
Wide and Single Section High-Supported installation instructions.
