An ammo can with a brain. The StopBox U-CAN is a lockable, portable gear box that opens with a finger code in one press, with no batteries, no electronics, and nothing to charge or fail.
- Mechanical Lock
- No Batteries
- One-Press Access
- 320+ cu in
- Lid Organizer
- Made in USA
The StopBox U-CAN is a high-capacity, lockable storage container built around StopBox's patented mechanical finger-code lock. Punch in your combination and the lid opens in a single press. Because the mechanism is entirely mechanical, there is no keypad to die, no battery to check, no app to pair, and no key to lose. It works the day you set it up and the same way five years later.
StopBox builds the U-CAN in Spokane Valley, Washington, from high-impact, glass-reinforced polycarbonate-ABS with steel reinforcement. It is the general-purpose box in their line: where the StopBox PRO holds one handgun flat, the U-CAN swallows a whole kit.
What fits inside
The interior runs 9 by 4.5 by 8 inches, better than 320 cubic inches. In practical terms, that is a full-size pistol, several loaded magazines, a couple hundred rounds, and your eyes and ears, in one box with a handle. The lid carries a removable organizer tray for the small stuff, and a built-in magnet keeps steel accessories where you put them instead of rattling around the bottom.
- Range kit: pistol, magazines, ammunition, eye and ear protection, all in one grab.
- Vehicle box: a locked container for the truck instead of a gun loose in a console.
- Preparedness kit: first aid, tools, documents, emergency gear behind a code.
- Shop and garage: the expensive small tools that tend to walk off.
How the lock works
The lock is the whole point. StopBox's finger-code mechanism is a deliberate press sequence with 81 possible combinations, set by you with the included hardware. It is child-resistant by design: random pressing does not open it, and there is no glowing keypad to attract curious hands. It is also fast for the person who knows the code, because a practiced combination becomes muscle memory you can run in the dark.
We will say this plainly, because it matters: child-resistant is not the same thing as a rated safe. The U-CAN is a locked, tough, portable container that keeps honest people honest, keeps kids out, and slows a thief down. It is not a 500-pound fire safe and it does not pretend to be one. For long-term storage of firearms in a home with determined access risks, a proper safe is still the right tool, and we will tell you that at the counter too.

Why we stock it
Dark Horse Guns & Ammo sells firearms, and every firearm we sell comes with the same conversation about storage. The U-CAN answers the most common version of it: something quick enough to actually use, secure enough to mean it, and portable enough to ride in the truck to the range. The fact that it runs with no batteries is what sold us. A dead keypad on the one day it matters is not a risk worth saving twenty dollars over.
Frequently asked questions
Is the StopBox U-CAN a gun safe?
No. The StopBox U-CAN is a lockable, child-resistant portable storage container, not a rated gun safe. It is built to keep children and casual hands out and to slow down theft, and it does that well. For long-term storage of unattended firearms, Dark Horse Guns & Ammo recommends a proper safe, and we are happy to talk through both at the counter.
Does the StopBox U-CAN need batteries or electronics?
No. The U-CAN uses StopBox's patented mechanical finger-code lock. There are no batteries, no keypad, no biometrics, and no app. Nothing about the lock can go dead or fail to sync.
How many combinations does the StopBox lock have?
The mechanical finger-code lock supports 81 possible combinations, and you set your own using the hardware included in the box.
How big is the StopBox U-CAN inside?
The interior measures 9 inches long, 4.5 inches wide, and 8 inches tall, which is more than 320 cubic inches. That fits a full-size handgun, several magazines, a couple hundred rounds of ammunition, and eye and ear protection at the same time.
Can I fly with the StopBox U-CAN?
TSA rules require firearms in checked baggage to be unloaded and locked in a hard-sided container, declared at the counter. The U-CAN is a lockable hard-sided container, and StopBox addresses air travel for its products. Rules shift and airlines add their own, so check current TSA and airline policy before you fly, and ask us if you want help reading them.
Is the StopBox U-CAN child-resistant?
Yes. The lock uses a deliberate press sequence that random pressing will not open, and there is no lit keypad to draw attention. StopBox designed it specifically so that quick access for the owner and resistance to curious children are not in conflict. No container replaces supervision and safe firearm habits.
Where is the StopBox U-CAN made?
StopBox builds the U-CAN in Spokane Valley, Washington. It is an American-made product from an American company.
Can Dark Horse ship the U-CAN to me?
Yes. The U-CAN is a storage container, not a firearm, so no FFL transfer is involved. Buy it from Dark Horse Guns & Ammo in Yerington, Nevada at the counter, or have us ship it to you directly.
