A job-site storage container is usually selected from nominal 20-foot or 40-foot units, both commonly about 8 feet wide outside, but those names do not describe the usable opening or interior. Choose from the largest item and handling method first, then verify the offered unit’s inside length, width, height and door opening before allowing for shelving, an aisle and safe delivery access.
