📞 435-828-7710The 20-foot container is the most popular size at Fort Knox — it's the right fit for most apartment moves, seasonal decluttering, and small business inventory. At 160 square feet with over 8 feet of height, it holds more than most people expect. Think of it as a one-car garage you can fill floor to ceiling.
Every 20ft unit at Fort Knox is a sealed steel shipping container — the same construction used for international ocean freight. Mouse-proof, spider-proof, dust-proof, and fireproof. Your belongings stay exactly how you left them.
The 40-foot container is the heavy-duty option — 320 square feet of sealed steel storage, equivalent to a full two-car garage. This is the size oil field crews, contractors, and families with large homes choose when they need real capacity. You can store an entire household including the garage workshop and still have room for seasonal equipment.
At $230/month, the 40ft container is significantly cheaper per square foot than renting two smaller units — and you get the convenience of everything in one place. With the 6-month deal, your effective cost drops to about $153/month.

Fort Knox containers are 8.5 feet tall. Use the full height — put heavy items on the bottom, lighter boxes on top. You'll be amazed how much fits when you stack efficiently.
Remove table legs, bed frames, and shelving units before loading. Flat-packed furniture uses a fraction of the space. Keep hardware in labeled bags taped to each piece.
Same-size boxes stack neatly with no wasted gaps. Medium boxes (18" × 18" × 16") are the best all-purpose size — large enough for most items, small enough to stack safely.
Leave a narrow path down the center so you can reach items at the back without unloading everything. This is especially important if you'll be accessing the unit during a long-term rental.
Stuff drawers, appliances, and hollow items with soft goods — towels, linens, clothing. Fill the inside of the washer and dryer. Every cubic foot of air is wasted space.
Put items you'll need first near the door. Seasonal items can go to the back. Heavy furniture and appliances along the walls, boxes in the center. Think about unloading day while you load.
Call James at 435-828-7710 before renting — he'll help you choose the right size based on what you're storing. If you've already rented and need to switch, James can typically move you to a different container with no penalty. He'd rather you have the right fit than pay for space you don't need.
You can, but it costs more. Two 20ft units are $260/month total vs. $230/month for one 40ft unit. The single 40ft container also gives you the convenience of everything in one place. The only reason to choose two 20ft units is if you need separate access — for example, personal items in one and business inventory in another.
A 20ft shipping container (8' × 20') provides 160 sq ft — similar to a traditional 10×15 or small 10×20 unit, but with the added advantage of being completely sealed steel construction. A 40ft container (8' × 40') provides 320 sq ft — equivalent to a 10×30 or larger. Both Fort Knox sizes are taller than typical storage units (8.5 ft vs 8 ft), giving you extra vertical space.
Yes. Shipping container doors open to the full 8-foot width of the container — much wider than the roll-up doors on traditional storage units. Sofas, mattresses, appliances, and even ATVs fit through easily with room to spare.
