Locking Mailbox Access For Mail Carrier

[Art Maydan]

I want to install a locking curbside mailbox for a triplex I’m managing. I see the list of approved USPS mailboxes, but I can’t find anything on how to get the mail carrier access. Does anyone know how to make it so that mail can be delivered to a locking mailbox? Thank you!

@Art Maydan I have that exact box. Each door has its own key that you give to the tenant (included), then USPS comes and installs their lock in that top hole, which allows the entire front of the unit to hinge open from the bottom for the carrier to toss mail into each of the 3 slots. No cost but it takes them like a week to come out.
