racks pigeon hole

A pigeon hole rack is a type of storage system which has been designed to store the products in racks that are in the shape of pigeon holes. It is very easy to identify a product and replace it in this type of storage system. These are like tabular forms in which there is a number of rows and each row consists of a number of columns. A very good example of this type of rack is a shoe rack in which a number of shoes are stored in pairs in each column.
