- Easy to install over a standard British letterbox opening
- Accommodates all normal letterbox mail, including newspapers
- The seal around the opening is airtight, thus starving the fire of oxygen. However, if the fire does persist, it heats the alcohol contained within a glass vial which breaks, activating the 100g fire extinguisher (FE36 extinguishant)
- Measures 525 (H) x 325 (W) x 125mm (D) and has a maximum mailing aperture of 70 (H) x 300mm (W)
- Replacement extinguisher refills are also available - see drop down
- For more auto-activating extinguishers see the and
- For businesses concerned about the threat of arson take a look at our Industrial Mailboxes and Slimline Size Mailboxes which are both available with an internal fire safety system to combat arson attempts
