Which one fits you

locking curbside box

Mail Boss Mail Manager (line)

A heavy steel post-mount box with a locking retrieval door and an anti-pry slot.

Not for: Households that receive large parcels or want a simple open box.

Check before you buy

USPS approval (curbside). Curbside boxes should be marked as Postmaster General approved. Carriers can decline to deliver to non-approved curbside receptacles.
Size. Choose large-capacity (T2-style) over standard (T1) if you get magazines or small parcels. Overstuffed standard boxes mean mail left out or packages taken back.
Material. Galvanized or powder-coated steel, or heavy cast aluminum, rather than thin plastic. Thin boxes dent, rust or crack, and plastic flags snap.
Security. Use a locking box with an anti-fish baffle where mail theft occurs. An open box gives no protection for checks and IDs.
