4. Set the second rafter (first inside rafter) in place and
secure it to the rafter feet.
NOTE:
After securing the inside rafter to the rafter feet,
position someone at each leg to stabilize the rafter as
the lift is removed.
5. Place a cross-connector (#102546) over the peak of
the inside rafter.

rafter.
6. Insert the first section of purlin (2 pieces of pipe)
through the cross-connector on the inside rafter and
the pipe strap at the peak of the end rafter.
IMPORTANT NOTE:
The purlin should extend through
the pipe strap at the peak of the end rafter by one-half
inch. Do not allow the purlin to extend beyond the edge
of the end rafter.
7. With the purlin in position, tighten the pipe strap at the
peak and secure the purlin in the pipe strap using a Tek
screw.
8. Measure the on-center rafter width to achieve the
proper rafter spacing and tighten the cross-connector
(#102546).
NOTE:
If needed, use a hammer to tap the cross-
connector and the purlin to center it between the
brackets that secure the struts.
9. After tightening the cross-connector, install a Tek screw
(FA4484) through the cross-connector and into the
purlin.
Position the Tek screw so that it also secures the
joint of the purlin pipes if possible
.
