Frequently asked questions
What are door knob components?
Door knob components are the visible knob trim and rosette pieces specified separately from the latch or lock body. They include the interior and exterior knob, rosette plates, and connecting spindle.
Why specify components separately?
Specifying components separately allows the knob, rosette, and underlying lock or latch to be matched precisely to the project — including custom hub sizes, fire ratings, and finish combinations not always available in pre-packaged sets.
How are knobs matched to latches and escutcheons?
Knob components are matched through hub size (typically 8mm or 6mm), spindle length, and rosette compatibility. Casson Hardware's specification team coordinates the right components for any project.
Does Casson Hardware support component specification?
Yes. Casson Hardware's specification team supports trade clients in coordinating knob components with latches, escutcheons, and lock bodies through the Trade Program.
Where can I buy door knob components in Canada?
