15ft Portable Storage Containers

Our 15' standard onsite container is popular with retailers looking for storage space but lack the outdoor area for a larger storage container. With approximately 140 sq. ft. of space, there’s plenty of space for equipment, tools, and/or inventory, and the 15' secure storage unit fits nicely into a single standard-sized parking space.  

Portable Storage Needs:

  • High value inventory
  • Seasonal supplies
  • Small equipment
  • Record boxes
  • Landscaping tools
  • Janitorial equipment


Portable Storage, Conex, or Sea Can: What's the Difference?


Portable storage containers have a variety of names including sea can, conex container, shipping containers and more. Learn more about these terms from Mobile Mini. 


Portable Storage Container: These containers are used for storing equipment, files, or whatever your business needs storage for. You can rent or buy portable storage containers depending on your short- or long-term storage needs. 


Conex Container or Conex Box: This term was coined during World War II. The Army was using these steel containers called transporters to ship cargo and goods to the front lines. Later, the transporters were called container express box system, also known as conex containers. 


Sea Can: This term was created based on shipping containers that travel by sea.
