Each MAX6MUM SECURITY letterbox has a black frame surround, with the flaps being made from aluminium. It has many features not found on standard letterboxes, including anti-vandal, anti-snap flap, anti-burgular and anti-scratch facilities:

Anti-Vandal: Each year, house fires are started by vandals putting fireworks through letterboxes:


Each MAX6MUM SECURITY Anti-Vandal mirror polished letterbox has the brushes outward facing (a feature no other letterplate in the industry has). This gives you 3 great benefits:

1- Having brushes on the front of the door acts as a visual deterrant to vandals. As the internal cavity is not easily accessible, it makes it alot harder to put lit fireworks etc. into the cavity

2- It is easier for postmen to navigate letters through the brushes, so you won’t end up receiving crinkled letters anymore.

3- The brushes stop draughts at the point of entry, making the letterplate draught-proof.

Anti-Snap Flap: Makes letterplate flaps snapping off a thing of the past


Each MAX6MUM SECURITY mirror polished letterbox flap can open to 180 degrees, meaning that it should not snap if listed up too far. Many letterplates available only open to 90 degress, so when too much force is applied when lifting the flap up, it causes them to snap off.

Ultra-flexible springs means that the letterbox can withstand thousands of openings without breaking, making them last even longer! An internal water seal also prevents water getting into the door or panel. which stops letters getting wet as they are posted through the door. The water seal also helps to prevent the flaps from pitting or rusting!


The hidden fittings of the letterplate made burglary very difficult as it is nearly impossible remove it from the outside. The blind bolts make external removal impossible.

Anti-Scratch Frame:

With the regular traffic this door hardware will get it’s only natural to worry about visible markings on it from scratches either from fitting or from everyday use. The matt coat helps make any markings nearly invisible to the naked eye. Also, the matt coated frame helps to conceal any scratches which are caused by screwdrivers at the time of installation.
