BOX/ PRESET LOCATION:

layout is known) or by using an electronic preset finder
(Cat. No. 480). Cut and remove carpeting or tile over box
or preset. Carpet may be saved for later abandoning.
2. Using a hammer, chip out the concrete from the mud
cap cover.
3. Strike the edge of the exposed mud cap with a blade type
screwdriver to deflect the cap inward.
4. Insert the screwdriver along the edge of the preset and pry
up removing the cap.
5. Remove any debris that may have fallen into the enclosure.
6. Grout around the opening if concrete does not break
away cleanly.

screwdriver blade into opening as shown.
2. Insert a wire hook into the arched opening to prevent the
knockout from falling into the duct.
3. Push screwdriver toward center of the preset, breaking
the tabs to release the knockout.

debris from the raceway.

PRO SERIES PRESET TRIM FLANGE INSTALLATION:

2. Attach the trim flange to the link straps with four #10 flat
head screws. Two lengths of screws are provided to
accommodate variations in floor thickness.
3. If installing on a tile or wood floor, apply a bead of sealant
around the underside of the flange to prevent water
leakage into the preset.
4. For a flush appearance with wood floors, cut an opening
1/8" [3.2mm] deep conforming to the trim ring perimeter
