Parts Desk Insights
Best Use Case: Best for replacing or upgrading an existing mortise lock set where the escutcheon and case dimensions must match and the door thickness falls between 1" and 1-3/8".
Common Issues: Measure before purchase: confirm your current cutout/backset setup matches the lock case and escutcheon opening dimensions, and verify you have (or can reuse) the correct #6 mounting fasteners for the mounting pattern.
