Wood trusses are pre-built components that function as structural support members. A truss commonly employs
one or more triangles in its construction. The wood truss configurations illustrated here are a representative
sampling. The number of panels, configuration of webs and length of spans will vary according to given applications,
building materials and regional conditions. Always refer to an engineered drawing for the actual truss design.
