Sargent LFIC construction core control key. This key DOES NOT operate the SFIC construction cores, it is for the LFIC construction cores only. Sargent LFIC construction cores are generally in HF keyway and marked with a dimple on the face, just above and to the right of the top of the keyway.
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.
Key will be stamped "C".
