Tips & Instructions
A few tips:

  • Keys are attached inside the letter flap of your letterbox for dispatch, please keep them somewhere safe until your letterbox is installed and ready for use
  • Although simple to fit, these letterboxes will need to be installed while building the wall, or bricks will need to be removed to retro fit, and then mortared in place. We would also recommend obtaining the advice of a qualified trades-person before purchase to ensure a product is suitable for your requirements.
