It is the absolute simplicity that is behind the idea of this lock that confers the ideal solution for all demands. By replacing the nucleus, you have the possibility to have a brand new lock, which excludes up front maintenance costs that you may have in case of break, loss or burglary and others which request to dismount the door for replacing.
Other points of strength are privacy of the three keys at Double Bit from 50mm, which are supplied with the nucleus in sealed wrapping; to the run of latches, which thanks to the shape, allow to have an equivalent of four turn just with 2 key turn, and to the shape, safe type which allow an easier transport, more favourite than the classical and big “long” keys.
To remind, at the end, the production of the same nucleus, whose main point, is made os a group of pressed layers, which grant a very high level of anti-manipulation.
