How to: Correctly install and use a mailbox

Part 1: Assembling the mailbox

1. Check all components
   Unpack the mailbox and check that all parts are included, such as the door, lock, keys and mounting hardware.
2. Assemble loose parts
   Attach any components that are not pre-assembled, such as the door, mail slot or lock, following the manufacturer’s instructions.
3. Test moving parts
   Open and close the flap and door several times and check that the lock operates smoothly before proceeding.

Part 2: Installing the mailbox

1. Choose the right location
   Place the mailbox in a clearly visible and easily accessible spot for the mail carrier, without blocking the pavement or driveway.
2. Determine the correct height
   Take ergonomics and postal service guidelines into account when setting the height of the mail slot.
3. Mark the mounting points
   Position the mailbox temporarily and mark the drill points. Use a spirit level to avoid installing it crooked.
4. Secure the mailbox firmly
   Use suitable screws and wall plugs for the surface. For freestanding models, mounting on a base or foundation is strongly recommended.

Part 3: Using the mailbox correctly

1. Use the mailbox as intended
   A letterbox is designed for letters, while a parcel mailbox is suitable for larger deliveries.
2. Always close doors and flaps completely
   This prevents water ingress, dirt build-up and unauthorized access.
3. Empty the mailbox regularly
   Overfilled mailboxes can become damaged and may cause delivery problems.

Part 4: Maintaining the mailbox

1. Clean the mailbox regularly
   Use a soft cloth and a mild cleaning agent to remove dirt and deposits.
2. Check locks and hinges
   Lightly lubricate moving parts when necessary to reduce wear.
3. Inspect stability and fixings
   Tighten screws if needed and ensure the mailbox remains stable and level.
4. Protect against weather conditions
   Regular maintenance helps prevent rust and material deterioration.
