Buying Guide
What should you consider when buying square crystal door knobs?
- Function vs. decoration: Choose dummy or passage knobs for aesthetic updates; opt for privacy knobs with a locking mechanism for bedrooms and bathrooms.
- Door compatibility: Confirm backset (2-3/8″ to 2-3/4″) and door thickness (often 1-3/8″ to 1-3/4″).
- Finish and style: Matte black, brushed gold, and satin brass finishes complement different decors from modern to vintage.
- Installation: Look for included hardware and templates; ensure screws align with your door rosettes and strike plates.

How to choose by room type
- Bedrooms: Prefer privacy knobs with an interior lock and an exterior emergency release for quick access in emergencies.
- Bathrooms: Privacy locking is essential for privacy; ensure the external mechanism is easy to operate.
- Closets and hallways: Passage or dummy options work well when no lock is required but a decorative crystal look is desired.
- Living areas and decorative doors: Dummy or passage versions can provide a cohesive design without compromising space or function.
