Start with the thing we would rather you did not pay twice for: a welded lockbox ships standard on every container we sell and every container we rent. It is in the price, along with delivery and leveling, and our FAQ says it in the same breath as no surprise add ons. If someone quotes you a lockbox as an upgrade on one of our boxes, they are quoting you something you already have.
So this page is not a sales page for a lockbox. It is about the layers that go beyond the one you already own, and about the security arithmetic of modifying a container at all, because most of what we get asked here is really a question about openings.
The container is already the hard part
It is worth understanding what you are starting from, because it is unusually good and it changes what is worth adding.
Cargo doors are set in a welded steel frame at the corner posts, which is the strongest part of the structure. They close onto a heavy gasket and are held by four vertical locking bars that engage cams at the top and bottom of the door, so the doors are clamped into the frame at eight points rather than latched at one. Everything is fourteen gauge Cor-Ten steel.
The welded lockbox is the piece that finishes it. It is a steel shroud welded over the lock area so a padlock sits inside a box rather than out in the open, which takes bolt cutters and pry bars out of the conversation for that lock. It goes on before the truck leaves our yard.
Which means the honest advice on a plain, unmodified storage container is often that it needs nothing further. The upgrades below exist for specific situations, not as a default.
Extra hasps and camera ready mounts
The hub lists what our shop fits: welded lockboxes, extra hasps, and camera ready mounts to keep what is inside locked down. Two of those are the ones people actually come for.
Extra hasps
A second and third hardened hasp welded onto the doors gives you more than one lock, and more than one lock is not really about doubling the difficulty. It is about time and noise. Anything with two or three separate locks in separate positions is a job that takes long enough to be noticed, and most opportunistic entry is a decision about how long something takes.
It also means you can key different locks to different people, which matters more than it sounds on a jobsite where a crew needs access to one thing and not another.
Camera ready mounts
Welded mounts in the right places so a camera or a light can go up without anyone drilling holes in a container you paid to have sealed. We fit the mounts and the conduit path as part of the build. The camera itself is yours to choose, and the electrical is roughed in ready for a licensed electrician to finish and have inspected in your jurisdiction.
The reason we do this as a mod rather than leaving it to a bracket and some screws is the same reason we do not let shelving get bolted through an exterior wall. Every unplanned hole in the shell is a leak you find later.
Every mod you add spends some security
This is the part of the conversation our shop cares about most, because it is where people get surprised.
A container's security comes from being a sealed steel box with exactly one hardened opening. Every modification that adds an opening spends a little of that. Not enough to be a reason to skip the mod, but enough that it should be a decision rather than a discovery.
- A personnel door is a second opening with normal door hardware. A commercial grade steel door in a welded steel frame is a serious door, and it is still the softer of the two openings.
- A roll up door is a rolling steel curtain with a latch. Fast and excellent to use daily, and not in the same class as cargo doors and a lockbox.
- Windows are the biggest single trade, which is why they belong on offices and retail builds and rarely on remote storage.
- Vents are the exception. They are small, shielded, and they buy you a dry container, which is a real benefit for no meaningful security cost.
If a build needs a lot of openings and also needs to be secure, the answer is usually to concentrate them on one face and put that face where it is overlooked, rather than to spread them around the box.
The free upgrade almost nobody uses
Where the container sits does more for its security than most of what can be welded onto it, and it costs nothing at all if it is decided before delivery rather than after.
- Point the cargo doors at something. A wall, a bank, a treeline, another container. Doors that cannot be opened fully cannot be worked on comfortably.
- Put the openings where you can see them. The face with the walk in door and the windows should be the face visible from the house, the shop, or the road you drive in on.
- Do not leave a working aisle. Space behind and beside a container is space someone can work in unseen. Tight against something is better than in the open.
- Think about approach, not just position. A container reachable by backing a vehicle up to the doors is a different proposition to one you have to carry things away from.
We ask about site access anyway, because the truck needs a straight pull in of roughly 65 feet for a 20 ft container and about 95 feet for a 40 ft, and the ground needs to take the weight. That same conversation is the right moment to decide which way the doors face. Once the container is set and leveled, changing its orientation is a delivery, not an adjustment.
Tell us the plan for the site when you book and we will set it the way you want the first time.
A few things worth knowing
Locks
A lockbox protects a padlock, and it works best with the kind of short shackle, hardened puck or disc style padlock designed to sit inside one. A long shackle lock in a lockbox is partly wasted, because the thing the shroud is protecting is the shackle.
Rentals
Rented containers arrive with the same welded lockbox as the ones we sell, because they are the same containers. If a rental needs additional security for the length of a job, tell us when you book rather than after it lands, and we can work it into the build.
Containers you already own
We fit security upgrades to containers you already own, provided they are structurally sound and wind and water tight. Bring the container to Woodlawn and we will assess it before quoting, or ask us to price a collection if hauling it is not practical. If an older container has a lockbox that is past its best, replacing that is simple work.
Extra hasps and mounts are usually among the mods that turn around in a few days. Bundled into a full build with doors, insulation, electrical and finished walls it becomes part of a longer timeline, usually one to a few weeks depending on scope and parts, in writing with the quote.
