  • The Sweet Spot for Commercial Storage

    The 13′ Storage Unit hits the sweet spot between capacity and maneuverability. With 884 cubic feet of storage space, it offers 30% more capacity than our 10′ unit while still fitting in most standard parking spaces.

    This is our most popular choice for equipment dealers, retail operations, and property management companies who need substantial storage without the footprint of a full 20′ container.

    The reinforced 28mm marine plywood floor is rated for pallet jacks and heavy equipment, making it ideal for commercial applications where durability matters.
