quadcon

Four is the number the whole design is built around

Four quadcons, latched together end to end, run about 20 feet total, the same length as one standard container. That's not a coincidence, it's the entire point of the design. The U.S. military needed a box small enough for a truck bed or a helicopter sling load, but built to the same corner castings as the container fleet already moving through every port, rail yard, and ship in the world, so the math had to land on a round number.

Each quadcon runs roughly 5 feet long, 8 feet wide, and 8 feet tall, the same width and height as a standard commercial container, just cut short. Group four together and a crane built for one 20-footer can pick up the whole set in a single lift, because the outer corner castings line up exactly where a 20-ft box would carry its own.

What that number tells you, and what it leaves out

Knowing that four quadcons equal one 20-footer tells you how the box gets handled. It tells you nothing about what's inside. Quadcons haul ammunition, water cans, rations, generators, and field communications gear, and the build varies with the cargo: some are open-top, some shelved, some sealed and insulated.

A quadcon shares the same corner-casting logic as its larger cousins in the modular family, the tricon and the bicon, which split the same 20-foot footprint into three units or two instead of four. All three exist so the military can mix cargo types on one flatbed or one chassis slot without breaking compatibility with standard container-handling equipment.

Why you won't find one on our lot

Containers Delivered sells and rents the commercial 20-ft and 40-ft steel boxes that show up on farms, jobsites, and storage lots across Virginia, West Virginia, and North Carolina. A quadcon is a specialized military unit built for a different job entirely, and we do not stock, sell, source, or price one. If a listing somewhere calls a box a quadcon, treat it as ex-military surplus, a different animal than the used or one-trip containers on our own lot.

If what you actually need is a standard box for storage, a jobsite, or a farm, read our guide comparing 20-ft and 40-ft containers to see which size fits.
