Decoder system for both
old 7 gauge Securefast locks where the curtain spins a full 360
degrees and the newer black BS version.
This system uses reader
keys to determine which of the five possible levers are present in the lock. A
key is then constructed using our revolutionary new system of milled brass key
bits that the user slides on a central shaft, then secures in place with the
outer sleeve handle. This means no pins to fall out, no grease needed and a
more accurate key can be copied on a key machine.
