Abstract: A gang mail box for an apartment building comprising an outer frame and an inner frame. The inner frame is pivotally connected to the outer frame which is secured to a wall of the building. A number of individual mail boxes corresponding to the number of apartments are mounted on and pivotal with the inner frame. These individual mail boxes are shaped so when the inner frame is pivoted, the tops of the individual mail boxes are exposed so the mail carrier can insert mail in them. Each mail box is provided with a hinged door having an individual mail box lock. A tempered steel security bar is provided to cover and conceal the tenants' locks on the individual mail boxes to prevent theft. This bar is hinged to the inner frame and is provided with a padlock for securing the bar in place.
