The Rooffrac® support rail was attached to the PSP <br />RoofTrac® structural atiachmentdevice with 3/8* SS hardware at four attachment points. The setup was attached to 2",(6" <br />wooden rafters using 5/16' x 3,1/2- SS lag bolts. The attachmentspans consisted of 48- frontto rear with structural <br />attachments spaced 72- on center. <br />TEST PROCEDURE(asshown in attached drawlngdetall): The test set up was top loaded to 50 lb/fti The setup remained <br />loaded for an approximate period of 30 minutes. The maximum deflection and any signs of permanent deformation were <br />recorded. The testsetup was then inverted and loaded to simulate the uplift 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 anysigns 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 cerUfles the Roofrrac® mounting system used with the modules, as specified above, withstands a 50 lb/ft* <br />static pressure load, equivalent toa wind speed of approximately 125 mph'*. The mountingsystem performed as expected. <br />Sincerely, <br />James R.
