Buying Guide
Key considerations for mortise-style door knobs
Finish and style should match existing hardware to preserve the interior’s character. Check door thickness compatibility and spindle dimensions before purchase. Durability matters; consider solid brass or zinc alloy for long-term wear. Privacy versus passage—privacy sets with a key option are ideal for bedrooms and bathrooms, while non-keyed sets suit living areas and closets.
How to choose the best option for your project
- Compatibility: Confirm door thickness (usually 1-3/8″ to 1-3/4″) and mortise lock compatibility with the included spindle and hardware.
- Finish: Bronze, antique brass, or oil-rubbed bronze finishes complement traditional interiors.
- Intended use: Privacy locks with keys are best for bedrooms and bathrooms; simple passage knobs work for closets and living spaces.
- Installation: Some sets come pre-assembled with screws and strike plates; others may require more setup. Consider universal-fit designs for easier retrofit.
- Maintenance: Corrosion-resistant metals (bronze, zinc alloy with protective coatings) reduce wear in high-traffic areas.
Practical questions to compare options
What door thickness does the set support? Does it include a spindle compatible with your mortise lock? Is a privacy key included, and on which doors is it appropriate? Will the finish match your existing hardware? How easy is the installation with the included hardware?
