Residents want to avoid any unintended recipients from accessing mail from their post box. This is especially important when apartment post boxes are located in communal areas, where neighbours or visitors are regularly passing by.

This means that property managers with responsibility for the building are looking for higher security letterboxes for apartments. Letterbox Supermarket was determined to offer a simple, cost-effective option.

The outcome is a universal baffle that can be used with most communal letterbox models. This retrofit option greatly limits access via the opening flap. This makes it harder for individuals to reach in and fish out mail that doesn’t belong to them.

You can purchase our baffle restrictors as an accessory with new communal letterboxes. Alternatively, they offer an affordable way to upgrade existing apartment letterboxes.

An anti theft baffle restrictor for apartment letterboxes

Do your letterboxes have a min 10mm folded edge protruding inside from the opening?

Is the thickness of the metal fold 1mm?

If so, the baffle plate can be fixed in place to provide added security to your letterboxes!

Simply push the baffle restrictor onto the fold. The profile offers the greatest security when directed upwards, however, this doesn’t work on all models. Test it out to be sure that mail can still be delivered into the hold. If there are any issues, turn it over, so the profile is directed down.

When satisfied that it will work, apply a quick-drying adhesive to the folded edge and then slide the baffle on. Once dried, it is ready to use. Simply repeat this process to enhance security on all of the apartment letterboxes.
