These abbreviations have the following meanings:

  • B/SB: blister packaging for self-service
  • EK: single box
  • gl.: one-key-fits-all (one key for multiple products)
  • vs.: individually keyed (only the keys supplied for that product will work)

These differences lie in the products’ locking operations. If multiple products use one and the same key, it is wise to use one of these locking operations. One key with the same number will then work for all locks. There are no technical differences between the products.

White and brown are always available, but increasingly silver is also being offered in the range. Information about this can be found under each version in the product descriptions.

ABUS uses colours similar to the following RAL colours: white: RAL 9016, brown: RAL 8014, silver: RAL 9006.

RAL colours are standardised colours, whereby a unique number has been assigned to each colour. This ensures exact reproduction of colours e.g. during painting, varnishing etc. and no variations. As such, the colour of the additional window lock or additional door lock can be matched exactly to the colour of the window frame.
