:FUNIRAC Unirac=Code-Compliant Installation Manual SolarMount <br />Step 4: Select Rail Type <br />Selecting a span and rail type affects the price of your <br />nstallation. Longer spans produce fewer wall or roof <br />oenetrations, However, longer spans create higher point load <br />forces on the building structure. A point load force is the <br />unount of force transferred to the building structure at each <br />zonnection. <br />[t is the installer's responsibilitv to verify that the building <br />itructure is strong enough to support the p0int load <br />·orces. <br />rable 10.
