The Front Loading Rotary Enclosures allow you to quickly and easily add P.O. boxes or Parcel Lockers into limited spaces. The Rotary Enclosures are great for apartment complexes, dormitories, and large corporations where wall installation is not an option. Enclosures can hold up to 5 P.O. Box Modules or 5 Parcel Lockers (the oversized Parcel Locker takes up 2 spaces). When the Master Lock is turned, the unit unlocks and rotates 180 degress to expose the open backs of the units. This allows PO Boxes and Parcel Lokcers to be loaded from the rear when there is no place to install them in the wall. After loading the boxes, the unit is again rotated 180 degress and securly locked. Customers then retrieve their mail from the front using their key. Boxes or Lockers are sold separately. Rotaries with Rack Ladder units can be used for Postal facilities and are USPS approved. For private distribution of mail, please order a Master Commercial Lock. Units are constructed of steel with a colored vinyl wrap. These custom manufactured enclosures are not returnable. Light Oak color.
