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?

They look like the plugs plumbers use to seal lines for pressure/standing water testing..... Someone got creative....

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.

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"The penny" has been replaced by "The ductape" in the minds of younger guys I think, Larry.
