How to check these dimensions

This entry covers the Euro-profile cylinder with round thumbturn in R6; the catalogue gives L=115 mm, C=55 mm, D=60 mm. Sides C and D differ by 5 mm, forming an asymmetric size; confirm the side functions and cylinder guard positions before reversing the installation orientation.

Side C is the thumbturn side marked in the catalogue; swapping the C/D values does not retain the same configuration.

Measure from both sides of the door and cylinder guards to the cylinder fixing screw centre, then compare with the C/D table and original drawing. Do not select solely by overall length.

Functions and ordering configuration

This configuration uses 30° DIN cam, with Round thumbturn operation inside. Pin and key materials are part of the series description; installation dimensions come from this specific catalogue record.

Brass number in this catalogue row: 888955607..5; nickel-plated number: 888955609..5. Specify the required finish when ordering.

• Provide the supplier with the series, complete order number, C/D order, required functions and key configuration together.
• Round-thumbturn, standard double-cylinder and double-function versions operate differently even when their dimensions match.
• Keep the original catalogue and subsequent revisions to check changes.

Limitations

• Check order numbers and dimensions together, using the corresponding catalogue and the manufacturer's complete ordering format.
• Confirm the finish and number of keys against the complete ordering configuration.
• This page does not guarantee compatibility with an existing door, site security level, local certification or current stock; check the installation drawings.
• The ..5 in the catalogue order number is retained from the original and denotes the five-key configuration in this table; the manufacturer must confirm the complete ordering format.
