Compactors also work on the principle as mentioned above and are used for storing small material in warehouses or for storing documents in office. Small compactors are enclosed from all sides and are centrally lockable thus ensuring security of item and documents.

Generally these racks are equipped with chain and sprocket mechanism and are operated manually by an ergonomically placed wheel provided at the front of each unit. In case of heavy loads, an option of electrically operated compactor is also available.
