Frequently asked questions
What is the difference between a wall-mount and a post-mount mailbox?

Are locking mailboxes available?
Yes. Casson Hardware carries mailboxes with integrated key-locking and combination-locking options for security-sensitive residential and commercial applications.
What materials hold up best for outdoor mailboxes in Canadian climates?
Solid brass, marine-grade stainless steel, weathering steel, and powder-coated steel are the most weather-stable choices for Canadian conditions. Casson Hardware confirms exterior-grade rating on each product page.
