When is a door knob the right choice instead of a lever?

When should I specify a door knob versus a door lever?
Knobs are typically specified for traditional and transitional interiors, secondary doors, and projects where a compact profile is preferred, while levers are required by accessibility codes in many commercial settings. Casson Hardware carries both formats from the same designers so a project can mix them where appropriate.
What functions are available for door knobs?
Casson Hardware stocks door knobs in passage (no lock), privacy (one-side lock for bathrooms and bedrooms), and entry (keyed lock) configurations, with the function type confirmed on every product page.
What finishes are available for door knobs at Casson Hardware?
Casson Hardware stocks door knobs in unlacquered brass, satin brass, brushed nickel, matte black, polished chrome, oil-rubbed bronze, and select living finishes. Finish availability varies by manufacturer.
