The gutter shown in this pic contains the main feed to a number of panels at a shopping center. Some extra holes were filled with.....some interesting 'plugs.' Anyone know what they were really intended to be used for?

Someone got creative.... [Linked Image]

What an electrician that did not have any 4" square blanks?

Anyway I will go with slicks thought or maybe plugs to be used when heating PVC for bending?

By the way I would also say they where punched out for either pulling or feeding the wires in the opposite pipes.

The folded one also.

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.

I wonder how many younger electricians would know what a "penny" is when used in electrical context?

it's easy, a penny is a high current fuse link that is usually protected by the wiring in case of a fault

"The penny" has been replaced by "The ductape" in the minds of younger guys I think, Larry.
