This is the technical data for the Mailsafe Anti-Arson Mailbox with extinguisher.

Product Code TSBOX01
Weight 7.10kg

Mailsafe® Anti-Arson letterboxes are the solution to the ever increasing crime of arson. Mailsafe will contain, detect and extinguish a fire in less than 15 seconds, before it has the chance to spread. Discretely placed within the letterbox is the Mailsafe Fire Extinguishing System. The fire extinguisher activates automatically when a fire raises the internal temperature of the letterbox. The Mailsafe extinguisher is a sealed thermosensitive polymer tube filled with the ozone friendly extinguishant FE-25. Mailsafe is simple to fit and has been designed to be fitted against the back of a standard letter plate.

The Mailsafe has been tested by Warrington Fire Research to determine the performance, when exposed to a series of ignition sources, each of which was designed to represent a potential method of arson attack.
The tests demonstrate that the 'Mailsafe' mailbox can successfully contain an arson attack and can provide significant protection against a serious fire developing within a building. If the mailbox had not been present, all of the potential arson attacks considered in the series of tests could have caused ignition of the contents behind the door (e.g. ignition of a floorcovering) and could have caused a major fire to develop.


Q. Just looking at the Mailsafe Anti-Arson Mailbox with extinguisher. The description says comes supplied with an optional anti-theft baffle to stop theft through the letterbox. Doe this mean this stops people putting their hand in your mailbox and stealing the mail?

A. Yes, the anti-theft baffle is designed to help prevent people from the outside stealing your mail either by hand or with a theft device.

Good quality product but there is scope of improvement. It arrived on time, well packed so no issues there but after looking at the design carefully I observed that the lock should have been placed in a way that its not accessible from the letter plate from outside. Guys if you are reading then please fix it.

Nice compact unit for tight entrances. Does inhibit some sizes of post so letters/ magazines wont drop in but stick out of the letterbox. Easy to install and use.

Very easy to fit and surprisingly attractive and unobtrusive considering what it is and the purpose it serves.
