Cut tie wire ( G) into four pieces of equal length. Insert wires through ends of turnbuckles. Twist each wire around
itself at least four times.
Drill holes for four ceiling anchors (see “Various Anchoring Methods"). Position the holes so that when the tie
wires ( G) when attached and taut will angle out at 15 O . Drill a fifth anchor hole directly above the center of the
ceiling tray.
Pull tie wires tight and attach to ends of ceiling anchors (or truss). Again twist each wire around itself at least four
times.
When this step is complete, the weight of the ceiling tray should be supported by the tie wires.
Note: 20’ (6.1 m) of tie wire (G) is provided. If space between the true ceiling and suspended ceiling is more than
36" (914 mm), additional wire (12 gauge annealed, steel, black) will be needed.
VARIOUS ANCHORING METHODS (Max. UL Load Capacity : 250 lbs. (113 kg)
Wood Joists or Beams
Drill 5/32" (4 mm) dia
holes 2" (51 mm) deep.
Fully insert eye bolts ( K).
Solid Concrete
Drill 1/4" (6 mm) dia. holes 1.5" (38 mm)
deep. Hammer in Concrete Anchor ( L) using
Rawl #3250 setting tool or equivalent.

Knockout panels are provid-
ed for electrical outlet boxes
and antenna leads.
Run the safety cable ( H) through the remaining
ceiling anchor. Pass each end through holes in
ceiling plate reinforcements and join with cable
clamp ( J). DO NOT TIGHTEN YET!
Suspended Ceiling Kit installation is now com-
plete. After all components (Jumbo Mount, Ex-
tension Column, etc.) and equipment (monitor,
VCR, etc.) have been attached, tension the tie
wires by adjusting turnbuckles ( F). Load must
be carried by tie wires - not suspended ceil-
ing runners. Finally, take up the slack in safety
cable (H) leaving it slightly loose. Tighten both
safety cable clamps ( J).
