Definition and scope
ASSA ABLOY describes a Euro Profile Cylinder as a locking component in a door-lock system that uses a key to control locking and unlocking. Euro profile describes an external shape; the name alone does not establish internal construction, dimensions or security performance.

Common operating types
The following distinctions by operation help with reading manufacturer catalogues; they are not a complete cylinder classification.
- Double cylinder: key operation on both sides.
- Thumbturn cylinder: key on one side and thumbturn on the other.
- Single cylinder: key operation on one side only. Confirm the manufacturer's use of single-cylinder and half-cylinder terminology against the product drawing.

Reading dimension and configuration information
When organising documents, record profile, both side lengths, operating type and associated connecting components separately, linked to the original drawing. This is this library's data-entry recommendation, not a universal dimension requirement for any model.
Differences from other components
The cylinder relates to key identification and operation; the bolt is the moving component entering the receiving location; the strike plate is mounted on the frame to receive it. Identify these separately when reading complete door-lock documentation.
Cylinder appearance alone does not establish whether the complete lock can be replaced. Check model-specific documentation for interfaces, dimensions and installation requirements.
Limits of this article
This article helps identify terminology and document types. It gives no burglary-resistance grades, endurance-cycle counts or certification conclusions; these require specific products and evidence.
Selection involving building use and access requirements must be verified for the destination region and application. Brand website scenario recommendations cannot be applied automatically.
