What tools do I need to install my letterbox?

The tools required will differ depending on not only the letterbox you have purchased, but the medium you are installing on/in. All fixings required for installation (e.g screws) are included with the letterbox. Our Pillar letterboxes generally require a hammer drill, 10mm masonry drill bit and spirit level for installation.  
 
The installation instructions for each letterbox will show any tools that may be required.
