How to compare within the series
A lever operates differently from a knob. For privacy functions, also distinguish inside push-button and thumbturn locking, and determine whether the configuration includes an interconnected deadbolt.
Reading dimensions and configurations
Door-thickness limits come from the official specification table; assembled dimensions are included only when clearly formatted. Similar dimensions do not make latches, fixings or door preparation directly interchangeable.
Limitations
- The official page shows a specific configuration; these specifications do not automatically apply to other keying systems, finishes or regional versions in the series.
- Specifications retain inches as used on the official page. Obtain the current dimensional drawing and complete order code for procurement and installation.
