Mailpro - Internal Use - Slim Anti Arson Mailbox, with 2xALF300 ext. (FE25) - White Finish SKU Number - CSM01022

The Mailpro `Slimline` anti arson mailbox (also known as an anti arson letterbox), offers a generous collection space yet is slim enough to allow its installation even on the majority of doors that open back against an internal wall.

  -  Stop fireworks or arson attacks through your letterbox

  -  Saves bending down to collect your delivered mail from the floor

  -  Eliminate fishing attacks through your letterbox - so your car keys, etc, are safe

  -  Keeps your mail safe - and PRIVATE!

The generous mail collection slot which fits over the inside of the letterbox on your street door, accommodates even bulky items posted through your door, such as directories or C4 padded envelopes, which drop fully into the internal collection chamber

Your mail is stored safely in the box until you unlock the easy access mail retrieval door and remove it, so you won`t find mail going missing and your mail is also protected against prying eyes!

This mailbox is fitted with dual, special "ALF" fire extinguishers, which instantly activate when burning material is posted through the letterbox, extinguishing the fire in seconds before it has a chance to gain a foothold.

Typically the extinguisher closest to the flame will rupture and kill the fire, leaving the second equinguisher available to tackle a secondary attack (police statistics indicate 70% risk of a secondary arson attack where the first attempt fails - before a response unit arrives at the site).

Unlike conventional extinguishers, ALF extinguishers are sealed for life and carry a manufacturers 5 year warranty (in tests however ALF extinguishers have proven to be effective, even on units which are over 10 years old!)

I recently purchased this mailbox for inside the main office door. It arrived within two days. Very surprised at how substantial and heavy it is. Nice finish, so it doesn’t look shabby. Fitting to the door is self-explanatory, however, there was no information included as to where the two extinguishers should be placed. Hopefully will do the job, should the unfortunate need arise.
