Seamless design and uncompromising functionality The Allux 600-B parcel letterbox impresses with its uninterrupted front - the flap for inserting parcels is located on the top of the letterbox. Another special feature is the removal door at the back of the letterbox. This detail makes it possible to integrate the letterbox as part of the property wall or as part of the entrance area. It allows the mail to be removed from the inside, eliminating the need to go to the letterbox in bad weather. Like all Allux letterboxes, this one is made of powder-coated steel and can withstand any weather. The built-in Ruko lock provides additional security and reliability.
