Fig. 29 --- Rounded End of Knockout
For the knockouts in the other locations on the door (top and
sides), tin snips can also be used along the door edges; however,
the preferred method is to use a hammer and screwdriver to strike
a sharp blow (See Fig. 31.) directly to the knockout tie points or
use a hammer in the upper left corner of the desired knockout.
(See Fig. 32.) Remove all burrs and sharp edges.
