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?

These are T&B Push-Penny® Plugs. I thought they were for plugging conduits. I never saw them used as KO blanks.

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.
