Legrand Wallduct Medical Raceway System Bodies - Manual (Page 9)

Step 1 With desired location selected, cut a hole
into bottom side (center) of duct ceiling body
9 13/16" [249.24mm] wide and 3 3/16"
[80.96mm] long for a standard 10" [254mm]
wide by 3 1/2" [88.9mm] deep drop out.
Adjust hole size accordingly for non-
standard drop out units.
Step 2 Drill four holes with a diameter of 9/32"
[7.144mm] to match with ceiling drop out
mounting holes. This can be best achieved by
placing the drop out onto duct body and marking
with a marker or pencil. These are the locations
for the palnut clips and machine screws.
SPECIFIC INSTRUCTIONS: DROP OUT UNITS
Drop out units are to be used for transitioning to cabinet or a perpendicular duct run.
Step 3 Place drop out unit into body and screw
into place with palnut clips and #10-32
machine screws. Installation is similar to
that of a coverplate.
Step 4 Attach the other duct body to drop out using
screws and coupling angles provided. Run
wires, wire retainers and close duct bodies
as necessary.
