Frequently Asked Questions
Is a master postal lock required?
No. A master postal lock is not required for this roadside mailbox. The front access panel is non-locking to allow USPS mail delivery, while the rear access door includes a lock to keep mail secure for retrieval.
Which pedestal or post should I choose for my driveway setup?
This mailbox works with both bolt-mounted and in-ground aluminum pedestals. The right choice depends on your driveway surface and installation preference. In-ground posts are typically used for permanent installations, while bolt-mounted pedestals are a good option for paved or concrete surfaces.
Will the mail slot fit padded envelopes or small parcels?
