Product Testing Inc. performed an independent test of the Truss DuraTrac Gutter System and found that the load capacity when using the Truss DuraTrac Gutter System was 11.3 times or 1130% greater than that of 5" gutters at full capacity and 7.6 times or 760% greater than that of 6" gutters at full capacity. These tests prove that the Truss DuraTrac system will not only handle the weight of a gutter full of water, but it can also take on heavy gutter loads caused by ice and snow.
