Legrand Wallduct Medical Raceway System Bodies - Manual (Page 6)

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.
Step 3 With cutout and holes made, place drop
out unit into body from top and screw into
place with palnut clips and #10-32 machine
screws. This installation is similar to that
of a coverplate.
Step 4 Adjust depth of drop out by loosening and
tightening the four #10-32 taptite screws on the
side of the unit until it sits flush as desired. Cut
desired hole size into drop out coverplate. Place
grommet supplied around field cut hole.
SPECIFIC INSTRUCTIONS: CEILING DROP OUT UNITS
Ceiling drop outs are intended for use with 10" [254mm] wide wallduct. The primary purpose is to allow wallduct
to sit flush with ceiling. Grommet all sharp edges to prevent wires from being damaged.
Step 1 With desired location selected, cut a hole
into bottom side (center) of duct body 8.75"
[222.25mm] wide and 8.75" [222.25mm] long.
NOTE: File all sharp edges and burrs on the wallduct that may cut
wire insulation.
