These practical mail boxes fit neatly on top of a table or workbench without taking up too much space. Made from 1.5 mm thick, mild powder-coated steel, the units come with lockable doors each of which is fitted with a cylinder lock and supplied with two keys. Each compartment has its own mail slot and there is space to add a label above the lock on each door. The pigeon holes are ideal for sorting all internal post in smaller companies but are perhaps better suited to sorting departmental mail in most organisations. To prevent people from leaving items on top of the lockers, a sloping top is sold separately.
