The Ultra Rail system has been evaluated for a Class A System Fire Classification for a Steep-Sloped Roof using Type 1 and
Type 2 modules. In order to maintain the System Classification, modules are clamped to the mounting rails between 0 and
12 inches from the top and bottom edges of the module.
The Ultra Rail system has been evaluated for a Class A System Fire Classification for a Low-Sloped Roof using Type 1 and
Type 2 modules. In order to maintain the System Classification, modules are clamped to the mounting rails between 0 and
16.3 inches from the top and bottom edges of the module.
The optional Array Skirt accessory has also been evaluated and the Ultra Rail system will maintain the Class A System Fire
Classification detailed above if installed with the Skirt.
Because the system was tested at 5 inches above the test roof fixture Ultra Rail can be installed without any height restric-
tions and will maintain the Class A System Fire Classification. See Rail Installation section for potential module-specific
height restrictions due to module temperature.
