The SCHLÜSSELWERK is built in 3 different sizes, which are designated as WORK SIZES S, Y and X.

FACTORY SIZE S 70-75 mm, our compact model, can be equipped with keys on one side and therefore small, light and handy.
FACTORY SIZE Y 80 – 85 mm is the middle size and can be equipped on one or both sides. The perfect compromise between handiness and high capacity.
FACTORY SIZE X 90 – 95 mm, the largest version. Is generally equipped with keys on both sides and is ideal for everyone who has a lot of keys to stow away. Very robust and present in appearance.

A perfect assembly is achieved when all keys on the left and right side can be folded completely into one another – similar to a pocket knife.
There should always be at least one spacer between the keys and on both sides of the emblem covers. Different key thicknesses can be compensated with additional spacers so that the same filling level is created on both sides at the end.

It is likely that not enough spacers (washers) have been inserted so that not enough pressure is being built up.
Therefore, always add enough washers so that the keys are pressed into the emblem covers when they are screwed together.

This is attached to the inside of the SCHLÜSSELWERK and is stored in our WORK NUMBER ARCHIVE.
