The Roofrrac® support rail was attached to the PSP <br />RoofTrac® structural attachment device with 3/8° SS hardware at four attachment points. The setup was attached to 2"xe" <br />wooden rafters using 5/16" x 3-1/2" SS lag bolts. The attachment spans consisted of 48" front to rear with structural <br />attachments spaced 72= on center. <br />TEST PROCEDURE (as shown In attached drawing detail): The test set up was top loaded to 50 lb/ft?. The setup remained <br />loaded for an approximate period of 30 minutes. The maximum deflectlon and any signs of permanent deformation were <br />recorded. The test setup was then inverted and loaded to simulate the upiift condition. The test set up was re-loaded to 50 <br />lb/ft?. The setup remained loaded for an approximate period of 30 minutes. The maximum deflection and any signs of <br />permanent deformation were recorded. <br />TEST RESULTS: <br />The maximum top load deflection was recorded at 0.313", with no permanent deformation. <br />The maximum uplift deflection was recorded at 0.250; with no permanent deformation. <br />This document certifies the Roofrrac® mounting system used with the modules, as specified above, withstands a 50 lb/fF <br />static pressure load, equivalent to a wind speed of approximately 125 mph**. The mounting system performed as expected. <br />Sincerely, <br />James R.
