Sargent S22 Bump Key

This is the Sargent S22 Bump Key - 6 Pin
We're offering this key in NICKEL SILVER form.  Nickel silver (same material as our SC19 and SC20) is a stronger metal that's perfect for this long key.
It has been machine manufactured to the deepest factory setting.

This is a MACHINE CUT Key.
Cut from a high grade key blank, and not from a recycled key!
