Knockout Covers

The EWB 212 is often used with a surface raceway (not provided). The wall box has gaps in
the top, bottom, and both sides to accommodate a raceway from any direction. The back
of the EWB 212 has four covers that can be used to fill gaps that are not used (see the
diagrams to the right).
1. Use small wire cutters to cut the plastic attaching the knockout cover to the wall box.
2. Ensure the knockout cover is in the correct orientation and slide it into place.
NOTE:
The larger knockout covers (for the top and bottom) have smaller
knockouts nested inside for running a small raceway to the top or bottom of
the wall box.

Holes are available for M3 and #6 grounding hex screws and nuts (see the diagram above).
The screws and nuts are not provided.
