BOX INSTALLATION
1. Determine the floor box location.
(Make sure the placement does not
interfere with obstructions below
such as floor joists, HVAC duct, light
fixtures, etc.) Drill a hole through
the flooring using a 4" [102mm] hole
saw (4 1/16" [104mm] actual).
2. For a flush installation in hardwood or
tile floors with the 895T or 896T series
covers - cut a 4 5/16" [109mm] diam-
eter, 1/8" [3.2mm] deep step in
the final floor covering.
3. Pull the nonmetallic sheathed cable or
armor clad cable up to and through
the 4" [102mm] hole.
NOTE: For air handling spaces allowed for that
application. See NEC 300-22(C). For
communications applications, type CMP
communication plenum cable is required
in raised floor plenums when wiring
methods as described in NEC article
300-22(C) are not followed.
4. Remove the appropriate 1/2" [12.7mm]
trade size knockout and attach a cable
connector to accommodate the wiring
system being used.
Attach the wiring system to the box.
To access the wiring cavity, open the
disposable cover cap and reseal after
use to avoid debris entry.
5. Orient the box to the desired rotation
and push into the hole. The box will
not turn once installed so make sure
the receptacle will be parallel or
perpendicular with any adjacent walls.

to trim around when installing carpet
or tile.

the disposable cover taking care not to
push the box through the opening.
