1.4 Regulatory Information
Fire Class Resistance Rating (ANSI / UL 2703)
The QRail system is intended for roof mounting over a fire-resistant roof covering rated for the application. The QRail fire
rating is valid for the following:

Class A for Flush Mounted Steep Slope Applications when using Type 1 or Type 2, Listed Photovoltaic Modules w/o
QSkirt

Class A for Flush Mounted Steep Slope Applications when using Type 1 or Type 2, Listed Photovoltaic Modules w/ QSkirt

Class A for Flush Mounted Low Slope Applications when using Type 1 or Type 2, Listed Photovoltaic Modules w/o QSkirt

Class A for Flush Mounted Low Slope Applications when using Type 1 or Type 2, Listed Photovoltaic Modules w/ QSkirt

Class A for 5° and above Tilt Mounted Low Slope Applications when using Type 1 or Type 2, Listed Photovoltaic Modules
w/o QSkirt

Class A for 5° and above Tilt Mounted Low Slope Applications when using Type 1 or Type 2, Listed Photovoltaic Modules
w/ QSkirt
This fire class rating requires installation procedures, which are in compliance with the included instructions. The QRail
system is intended for roof mounting over a fire-resistant roof covering rated for the application. The QRail fire rating is valid
for all roof slopes for Flush Mounted Systems and roof slopes equal to or less than 7° (1:12) for Tilt Mounted Systems. The
fire class rating is valid for systems installed at any height above the roof deck, with or without optional skirt.
Grounding & Bonding (ANSI / UL 2703)
This racking system may be used to ground and/or mount a PV module complying with UL 1703 only when the specific
module has been evaluated for grounding and/or mounting in
compliance with the included instructions.
Mechanical Load Rating (ANSI / UL 2703)
The QRail system has been mechanically tested according to UL 2703
Edition 1 to the following load ratings:

Downward Pressure: 10 PSF

Upward Pressure: 5 PSF

Down-Slope Load: 5 PSF
