Anti Arson - Mailpro

`MailPro` Anti Arson Mailbox/Anti Arson Letterbox

With over 200,000 arson attacks on properties in the UK every year, your building is potentially at risk ...and remember over 60% of businesses that suffer a major fire, fail within 18 months of the event - don`t let the arsonist beat you!

Protecting your letterbox against arson attack is key, as for most premises the letterbox offers an easy and inviting target for the would be arsonist. 

Targets include controversial establishments such as animal testing laboratories, government buildings, schools, shops, offices and even domestic premises. 

Perpetrators include activist groups, disgruntled customers, criminals out to get even, angry neighbours or just mindless vandals, but in any event, the result of an arson attack can be devastating and each year they cause death and serious injury as well as millions of pounds worth of damage to property.

Our MailPro (Mail Protector) range of anti arson mailboxes offer a simple yet effective solution to the threat. They are available in various sizes and each is fitted with one (or two) of our unique sealed for life "ALF" extinguishers. 

Dual Fire Extinguisher Option 

A high percentage of arsonists (police figures indicate up to 70%) try a secondary arson attack if the first attempt fails and before Police or Fire response personnel arrive at the scene. The MailPro Anti Arson Mailbox, when fitted with dual extinguishers offers the added protection of being able to defeat the second attack with the unused extinguisher!

Special Fire Extinguisher 

The ALF extinguisher is a sealed for life unit which unlike conventional extinguishers does not require an annual pressure test to check it is ok. It consists of a special thermoplastic tube filled with an ozone friendly extinguishant gas stored under a safe pressure Each ALF unit comes with a full five year manufacturers guarantee (although units over 10 years old have been tested and proven to be operationally effective).

Keying Options

The locks used on our Mailboxes, typically offer 2,000 different key patterns (differs). Units are normally sold with random key patterns, e.g. if you buy 5 boxes the chances of any one key fitting the lock of another box is 2,000:1. For customers purchasing multiple units, we offer an optional suite keying service - please ask for details.

See About locks & keying for more information on keying options.

Replacement MailPro ALF extinguishers

The internal MailPro which is designed to fit on the inside of a street door and collect mail delivered through the letterbox is available in two model sizes:

The "Slimline" unit is ideal for use in domestic environments or where the door to which it is attached opens back against an internal wall.

The "Large" unit offers extra capacity for the busy business environment where larger mail deliveries are likely.

Both models however are designed to fully accept a large C4 size padded envelope so you can be sure that you won`t end up with letters sticking out of your letterbox because they are too long to fit inside.

Model  HxWxD mm  Weight

Slimline  500x320x100  6.5kg

Large     500x320x150  7.5kg

Anti Arson MailPro models designed to be mounted externally i.e. to an external wall or post (which means the letterbox in the street door can be sealed to protect against arson attack), are also  available (see below).

All MailPro models can be fitted with a single or twin ALF extinguishers, and of course, replacement extinguishers are available as required.
