What is the answer of this question? please help

1 On Corbin Large Format Removable Core, the driver size: C？
A is a standard .243 regardless of stack height
B varies based on the pin stack
C is not important in the Large Format
D must be an even numbered pin

The answer is a mix of A and B. NON control chambers use a .247 driver and control chambers use a variable driver depending on the stack height.

I would suggest that you download the Corbin/Russwin cylinder manual from their site. It will give you the factory key depths and equate the pins to a universal pin kit using the chart. Then you can use their formula to pin the core.

Depends what defines "C". However by process of elimination based on common sense we can eliminate 3 choices IMO.

A. I would eliminate this simply because no system I know of uses a constant pin height and just from memory Corbin uses a .247" pin in non control.
C. I would eliminate because if anything stack height and pin choice is more important in LFIC pinning.
D. Eliminate this. Corbin is a one step system.

So my somewhat educated logical guess, not knowing what is meant by "C" would be B.

Thank you very much

Where did you get this question? I don't want to ruin a teacher job by giving away cheat sheets. After you tell us, I'll move this thread in a restricted access area.

Thanks

EDIT: nevermind, I saw your other post where you explain the situation.
