Most popular type of storage rack
Pallets are supported between load-supporting beams
Special attachments and decking can be used to make the racks capable of supporting other types of unit loads besides pallets (e.g., coils, drums, skids)
Selective racks can be used for the following types of storage:
Standard—single-deep storage using a counterbalanced lift truck
Narrow-Aisle—storage using a narrow-aisle lift truck
Deep-Reach—greater than single-deep storage (typically double-deep storage)
