Innovative baffle door accepts small parcels and deters fishing. Best for households needing strong curbside security and the ability to receive small packages without sacrificing mail privacy. Limitation: larger parcels may require alternative delivery arrangements if beyond the baffle capacity.
Who it’s best for and why
Best for homeowners who want robust vandal-resistance and USPS approval in a compact curbside unit. The anti-pry design and sturdy galvanized steel help deter common theft methods while remaining weather resistant.
Caution
Note that very large parcels may not fit through the baffle—plan for parcel deliveries that fit into the box or use an alternate delivery location for oversized items.
