Why do you only offer a small range of external post boxes?

Over the years, Mailboxes GB has dealt with a number of European post box manufacturers. During this time, the 2000 series and the 6000 series of letter boxes have proven themselves to be the most suitable products to withstand the British climate.

Water ingress can be a problem with some units, but the production methods employed in the manufacture of the 2000 and 6000 series of letter boxes means that there are no small holes where rainwater can penetrate.

Furthermore, the 2000 series of mailboxes have a waterproof seal to the back and sides to ensure that they are completely watertight.

Security is also an issue with external post boxes. The 2000 and 6000 series both employ anti-theft lips to the aperture, and in the case of the 2000 range, this is a particularly robust feature.

We need a secure post box for parcels

The Parcel Drop Box is available for sale online here. With a three point deadbolt locking mechanism and an anti-theft cantilever baffle, it is by far the most secure method of delivering small parcels to a mailbox.
Unlike other systems on the market, the Parcel Drop Box does not require the postman or post woman to make the unit secure once a package has been delivered. Furthermore, the Parcel Drop Box can accept multiple deliveries, unlike others on the market which can only accept a single delivery, once locked by the postman or post woman..
