Step 5 Screed to top of box surface. Hand troweling

recommended near box edges.

Step 7 If service access between adjacent compartments

is required, remove KO between compartments

and add grommet (not included).

Step 9 Terminate and mount devices.

Step 8 Locate and pull wires and cables.

Step 6 Remove mudcap.

CAUTION: Do not dislodge or shift box with jobsite traffic

or concrete vibrations.

NOTE: If box is over-poured or the top plate is below

the concrete surface, follow these steps:

1. Remove and retain mudcap and mudcap

mounting screws. If mudcap is bent during

removal, flatten within reason.

2. Install one or more 1/8" thick spacers, Cat No.

RFB119-TS (available separately), until the top

one is flush with the concrete surface.

See Step 19 for illustration.

3. Replace mudcap on top of spacers and secure

with mounting screws. Duct tape any cracks or

seams where concrete may enter.

4. Pour concrete patch around the perimeter of

the spacers and level with the concrete floor.
