Frequently Asked Questions

AI
Most homeowners install them, but it is essential to check if your mailbox is installed at the correct height and distance from the curb to meet postal regulations. If the lock prevents the carrier from depositing mail, the carrier may refuse to deliver.
A standard secure mailbox is designed for letters and magazines, a while a parcel locker is significantly larger and often features a separate drop-off compartment for packages, preventing them from leaving the porch.
Heavy-gauge steel and cast aluminum are preferred for durability and weather resistance. Look for models with powder-coated finishes to prevent rust and rust-through over time.
