fully installed and secure.
9. Place the mounting plate back over T-bar rails, so that
the hole in the tile aligns with the pipe adapter plate. If
necessary, loosen the lock nuts on the pipe adapter plate
and readjust the plate to align over the hole. If you wish
to fit the anti-vibration pads, follow step 10 below. If not,
just tighten down the lock nuts and proceed to step 13.
N DO NOT rest, or lean on the mounting plate or
suspended ceiling grid when attaching turnbuckles, tie
wire, or drilling into ceiling.
10. To mount the four optional self adhesive anti-vibration
pads, completely unscrew the lock nuts on the adapter
plate, and remove the top section only.
11. Peel and attach the pads to the underside of the adapter
