pre-punched holes at the top of each center connector. At the
end rafters, flush the ridge base extrusion with the outer face
of the center connector. When flush, apply washer & lock nut
and tighten. Repeat process for intermediate rafters. After
ridge base is securely installed, place a tek screw at each
rafter on each side of the base as shown in fig.4. It must be
placed in center of center connector for the roof extrusions to
