ASSUMPTIONS AND USE DETAILS
• Pressure limits refer to Up, Down, Downslope, and Lateral PSF.
• See Design Pressure table appendix for representative geographic pressures or refer
to
PRESSURE LIMIT MODIFICATION GUIDELINES
• Portrait Module Height 65 inches
• Landscape Module Width 39.4 inches
were calculated using a module size of 39.4in x 65in
• 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)
Pressure Tables for Flush Mounted Systems at unirac.com.
For each load direction, index the Allowable span for which the Allowable
Pressure does not exceed the Design Pressure.
The Allowable Span shall be the minimum of that for each load direction
Pressure limits apply to all roof zones.
Solarhooks are not recommended for use in hurricane zones.
Tabulated allowable pressures assume continuous rail spans and may need to
be divided by 1.25 for some rail span configurations.
Pressure limits were calculated from the allowable Solarhooks loads, which are
provided below for reference.
