Frequently asked questions
What is the difference between a mortise lock and a tubular latch?
A mortise lock is a self-contained lock body installed into a deep mortise pocket cut into the door edge, common in heavier and higher-security doors. A tubular latch is a smaller cylindrical mechanism installed in a simpler bored hole, typical of lighter residential doors. Casson Hardware lists the lock body type on every product page.
What is the difference between privacy and entry locks?
Privacy locks operate from one side only — typically a thumbturn used for bathrooms and bedrooms. Entry locks use a keyed cylinder for exterior or main interior doors requiring keyed access.
Which brands of latches and locks does Casson carry?
Casson Hardware carries Baton (European mortise locks), SAB / Hooky (Italian high-end mortise and hook locks), Accurate (American architectural locks), and select coordinated lock components from broader hardware brands.
How are latches matched to lever or knob hardware?
Latches must be coordinated with lever or knob trim through hub size (typically 8mm or 6mm), backset dimension, and faceplate profile. Casson Hardware's specification team can confirm the right latch for any lever or knob in the catalog.
Does Casson Hardware ship latches and locks across Canada?
Yes. Casson Hardware ships latches and locks to all Canadian provinces and territories from our Toronto warehouse, with delivery to the United States also available.
Where can I buy designer door latches and locks in Canada?
