Mailbox lock replacement
A mailbox lock must fit the door thickness, fixing arrangement and internal cam position.

Mailbox lock replacement — renew the mailbox cylinder while retaining cam, with site access, working hours and protection requirements planned, with the installation method, protection and finishing details planned.
Check how the lock engages without obstructing contents or the surrounding box. Identify the mailbox and whether it can currently be opened.
