ASSUMPTIONS AND USE DETAILS
• Pressure limits refer to Up, Down, Downslope, and Lateral PSF
• Pressure limits apply to all roof zones
• Solarhooks not recommended for use in hurricane zones
• See pressure table appendix for representative geographic pressures or refer to Unirac
Pressure Tables for Flush Mounted Systems on unirac.com
• Allowable Loads:
PRESSURE LIMIT MODIFICATION GUIDELINES
• Portrait Module Height 65 inches
• Landscape Module Width 39.4 inches
• Pressure limits provided above were calculated utilizing a B module size of 39.4in wide x 65in
long
• These pressure limits may be increased or decreased linearly.
• To modify pressure limits provided, follow these simple steps:
1. For portrait modules, multiply the given pressure limit by (65" / New Module Length)
2. For landscape modules, multiply the given pressure limit by (39.5" / New Module Width)
