Remember…
The integrity and accuracy of the first
row of main tees will ultimately determine
the quality of the completed installation
so be sure to check the integrity of the
completed row.
Tip: Extra care at this point will prevent
alignment problems throughout the rest
of the installation.
Be sure to use the appropriate flush-cut
main tee at the end of the row as specified
on the ribbon drawing.
Examine the completed row from the side
to ensure that the hanger wires are plumb. Wires should hang straight and plumb
within 1 in 6, about 10 degrees. If hangers
need to be relocated, move them now.
Examine the completed row end-on. It
should be straight with no waves. If you
need to install additional hanger wires,
install them now.
Tip: If necessary, you can punch or drill
extra hanger holes into the main tee to
ensure plumb wires.
Important…
You will be using this first row of main tees
as a template for hanging subsequent
rows, so take extra care to ensure proper
wire spacing before moving on.
Examine the row of main tees from the
side again. The curve of one tee should
flow smoothly into the curve of the next.
If the curves are not flowing smoothly,
adjust the hanger elevations either up or
down at the joints.
It’s important that the first row of main
tees remains stable during the entire
installation process. So, as a final step
in this first part of the installation, install
temporary bracing to the ceiling or
walls, if necessary, to ensure that the
row remains straight and rigid.
