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 ll gaps that are not used (see the
diagrams to the right).

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.
