Parcel letterbox for stand and wall mounting The Allux 500 is a smaller version of a parcel letterbox and is suitable for both wall and stand mounting. However, a suitable standing star is not included and can be purchased as an accessory. The opening for inserting mail is located on the top. Smaller parcels can also be posted here. The door for removing the mail is secured by a Ruko security lock, so the parcels are kept safe. The housing is made of galvanised steel with a powder-coated finish. The material is therefore particularly robust and can withstand all weather conditions.
