These are T&B Push-Penny® Plugs.
I thought they were for plugging conduits. I never saw them used as KO blanks.
Plug, Conduit, Connectors (Push Penny® Plugs)
Economically seal out grout and plaster from
any fitting or raceway conforming to CSA
dimensional tolerances. Made of flexible plastic,
they push into place and are held fast by
pressure against internal surface of fitting or
raceway. Eliminates need for separate capped
bushing or steel penny and bushing.
Application
[*] To plug open end of conduit or connector
in order to prevent ingress of
trash, dirt or moisture during construction
and remodeling.
Features
[*] Wide range of application; can be
used with rigid metal conduit, intermediate
metal conduit, electrical
metallic tubing, all connnectors and
all bushings.
[*] Designed to stand up to normal
handling and is functionally unaffected
by moisture.
