Sargent SFIC construction core operating key. This key DOES NOT operate the LFIC construction cores, it is for the SFIC construction cores only. Sargent SFIC construction cores are in E keyway and marked with a blue face.
Note: On rare occasions, some people change the pinning in their construction cores. These keys will only work on construction cores using the original/standard pinning. We recommend you make sure these keys will work for your application before ordering.
