Figure 35. This graphic is from the ASSA MAXIMUM+ SFIC cylinder pinning Excel file. ASSA Pin Stack Calculator Now that you see the hows and whys of calculating the pin stacks for the ASSA SFIC, it is not difficult at all. But, to further assist you, ASSA created an Excel calculator that can take the CK, MK and CTRL key bittings and quickly whip them up into six useable pin stacks in a jiffy. Notice the two green boxes. This alerts you to the fact that your predetermined control key bitting may not be useable within this system if it appears red in color. If so, alter it so that the cut is deeper. Furthermore, ASSA requires at least one cut on the control key to be deeper than any operating key cut. Note that the MACS of 5 is shown as a reference. Figure 35 il- lustrates this. You can access it via the LSA Michigan website. NOTE: Since this is an Excel file and not an .EXE file, you will need to download it, save it to your device (desktop, computer, phone, etc.) and open the file. You will need Excel soſtware on your de- vice to work it. You cannot open it online and expect it to work! Conclusions ASSA has created a revolutionary new SFIC system, A5, that can accommodate many more bittings than any other existing SFIC system, without the use of side pins, side cuts or any other mechanical add-on device. They were able to successfully use their existing .0235" increment system and .150" spacing to ef- fectively offer an SFIC with a standard pin diameter of .108” that can retrofit existing SFIC hardware.

Happily, ASSA has stepped up to the plate at a time when SFIC is as common to locksmiths as bread and butter, and options are extensive, as we have seen over the last century. But, when a manufacturer can think outside of the box, the ramifications for the industry are striking. It’s a further indication that SFIC isn’t going anywhere anytime soon… other than becoming even more expansive than it already is. Special thanks are extended to: ASSA, Inc.
