Notes: <br /> Tables are based on strength of the InvisiMount rail and approved roof attachment in the Engineering Summary Letter <br />of this document, in conformance with IBC and referenced standards. <br /> The color of a given cell indicates the area on the module where clamps may be installed. Green cells allow clamps to <br />be installed in Portrait or Landscape orientations; Orange allows clamps to be installed only in Portrait; Blue allows <br />clamps to be installed only in Portrait within the given dimensions from the edge. Refer to the key at the beginning of <br />this document for more details. <br /> Maximum allowable cantilever is equal to 1/3 of the allowable span. <br /> Wind speeds are ultimate values in mph, as defined in ASCE 7. Wind pressure coefficients are derived from ASCE 7 <br />Chapter 30. <br /> User is responsible for verifying the strength of the roof. <br />Document #524734 Rev F, Vol. 8 70 SunPower Proprietary <br />Exposure C <br />Ground Snow (psf) 0 <br />Roof Height (ft) 30 <br /> INVISIMOUNT ALLOWABLE SPANS - ZONE 1 (IN) <br />Slope → 9.46 ° 14.04 ° 18.43 ° 22.62 ° 26.57 ° 30.26 ° 33.69 ° 36.87 ° 39.81 ° 42.51 ° 45 ° <br />Speed↓ 2:12 3:12 4:12 5:12 6:12 7:12 8:12 9:12 10:12 11:12 12:12 <br />90 96 96 96 96 96 96 96 96 96 96 96 <br />95 96 96 96 96 96 96 96 96 96 96 96 <br />100 80 80 80 96 96 96 96 96 96 96 96 <br />105 80 80 80 96 96 96 96 96 96 96 96 <br />110 80 80 80 96 96 96 96 96 96 96 96 <br />120 72 72 72 80 80 80 80 80 80 80 80 <br />130 48 48 48 80 80 72 72 72 72 72 72 <br /> <br /> INVISIMOUNT ALLOWABLE SPANS - ZONE 2 (IN) <br />Slope → 9.46 ° 14.04 ° 18.43 ° 22.62 ° 26.57 ° 30.26 ° 33.69 ° 36.87 ° 39.81 ° 42.51 ° 45 ° <br />Speed↓ 2:12 3:12 4:12 5:12 6:12 7:12 8:12 9:12 10:12 11:12 12:12 <br />90 80 80 80 96 96 96 96 96 96 96 96 <br />95 80 80 80 80 80 96 96 96 96 96 96 <br />100 72 72 72 80 80 96 96 96 96 96 96 <br />105 64 64 64 80 80 80 80 80 80 80 80 <br />110 48 48 48 72 72 80 80 80 80 80 80 <br />120 32 32 32 48 48 72 72 72 72 64 48 <br />130 32 32 32 32 32 48 48 48 48 48 48 <br /> <br /> INVISIMOUNT ALLOWABLE SPANS - ZONE 3 (IN) <br />Slope → 9.46 ° 14.04 ° 18.43 ° 22.62 ° 26.57 ° 30.26 ° 33.69 ° 36.87 ° 39.81 ° 42.51 ° 45 ° <br />Speed↓ 2:12 3:12 4:12 5:12 6:12 7:12 8:12 9:12 10:12 11:12 12:12 <br />90 80 80 80 80 80 96 96 96 96 96 96 <br />95 64 64 64 80 80 80 80 80 80 80 80 <br />100 48 48 48 80 80 80 80 80 80 80 80 <br />105 48 48 48 64 64 80 80 80 80 80 80 <br />110 32 32 32 48 48 72 72 72 72 72 72 <br />120 32 32 32 32 32 48 48 48 48 48 48 <br />130 0 0 0 32 32 32 32 32 32 32 32 <br /> <br />1931 W <br />Rd - 208/07/23
