According to the Association of Chief Police Officers (ACPO) there are three distinct crime risks associated with letterflaps in doors. Fishing (theft via a letterflap), Lock manipulation (the ability to open the lock via the letterflap), and Arson (a firework or flammable liquid poured through the letterflap).

There are continually shocking stories in the news of people living in fear of these crimes.

We were approached by various Arson task force teams in the UK to produce a solution. We now have 3 options - 1, for domestic/ private use, FL05, a heavier duty Police Preferred Product, and Homeguard, a long established product of ours used to fit at the rear of a front door to contain mail and fire which can be fitted with a fire extinguishing tube. We also manufacture an extensive range of over 120 models of mailboxes for surface mounting, recessing and through the wall applications, including a FIRE RATED range. All made in the UK.
