These boxes are great! Coming from a flatbed dually pickup with ample tool storage, I chose to go with these boxes on my new truck and am very happy I did. They are easy to install and customize, great quality, and look fantastic. I will definitely buy another set of these boxes in the future.
I purchased the 32” tool chest to use as a road box. I am 100 percent satisfied with the quality of the tool chest and the customer service I received from Brian at 12-D tool box sales in Paris, MO.
The box holds 5 inch grinders in the bottom drawers perfect for people that work out of their trucks im impressed by thr quality so for planing on ordering more
I love my side tool boxes. I'd been looking for something to hold all my tools and still be able to fit a pallet in my bed. 12D was easy to work with. I had some issues with the shipping company and 12D quickly resolved it for me
I’m very happy with my tool box and glad I found y’all on the internet
Tool box quality is awesome compared to montezuma. 12 d has the best price point on the tool box that I could find in the United States as well
Very well made
Very pleased. I have just one question. Is there another way to lock them if your tail gate malfunctions.
The pictures do not do it justice this toolbox is the real deal. It is built well and will last.
Love the setup. These guys are great to work with fast and just honest hard working people.
Perfect hight for under a tonal cover. Plenty of room for all my ratchet straps and extra hitches. And more room than I know what to do with.
ONE BOX. FULL BED
The 12D Flat Truck Bed Toolbox is designed to maximize the usable space across the width of your truck bed without getting in the way. It sits flush behind the cab and mounts just above the bed rails, keeping your bed floor entirely open for cargo, tanks, or trailers. It avoids interference with wheel wells or fifth-wheel hitches, making it the ultimate low-profile, full-access storage solution.
BUILT STRONG.
Proudly fabricated in Manitoba, these boxes use 1/8" aluminum construction and 100% TIG welding — no shortcuts, no spot welds. They're hand-built by tradesmen who use trucks like you do.
- Fabricated in Manitoba, Canada
- 1/8” rustproof aluminum — no paint, no corrosion
- Fully TIG-welded seams, no rivets or tack welds
Ready for Racks, Tanks, and Gear.
This isn’t just a toolbox — it’s a system-ready component. Whether you’re running auxiliary fuel tanks, bed racks, goose-neck trailers, or fifth-wheel hitches, this toolbox stays out of the way.
DESIGNED BY USERS
Every detail of the 12D Flat Bed Toolbox — from the no-rust aluminum to the gasketed lid — comes from real-world user feedback. This isn’t a big-box brand with gimmicks. It’s a purpose-built product from a small business that answers the phone.
Have a Question?
You're not alone—our customers often have the same questions when deciding on the right 12D toolbox. Below are the answers to the most frequently asked questions, drawn directly from real customer conversations.
Product Fit & Customization
Yes—12D Toolboxes are designed for a wide range of trucks including Ford, Ram, Chevy, Toyota, and more. Our standard sizes work for most full-size pickups, but we also offer custom fitment if needed. When in doubt, just send us your truck's year, make, model, and bed length and we’ll confirm fitment.
Yes. Every 12D Toolbox is built from thick aluminum with fully welded seams and automotive-grade weather seals. They're designed to handle rain, snow, and rough use in job sites or off-road conditions. Customers have put them through everything from construction use to overlanding without issues.
Yes—we can do custom widths, depths, and even internal features like drawers, shelves, or lighting. Just shoot us a message with your ideas or sketches and we’ll quote it out. Custom orders may take a bit longer, but we love building one-offs that match your exact needs.
Ordering, Pickup & Installation
Absolutely. Many customers choose local pickup from our shop in Missouri. Just let us know during checkout or via text that you prefer pickup, and we’ll coordinate a time that works for you. It's a great way to save on shipping and see the product in person.
Most in-stock toolboxes are ready for pickup or ship out within a few business days. For custom orders or not in stock items lead times can vary but expect around 8-weeks due to extremely high demand. If you're in a rush, just ask—we’ll give you an honest timeframe and work with you to meet any deadlines.
Each toolbox includes mounting tabs or brackets for easy installation using standard bolts or self-tapping screws. If you’re not sure how to mount it, just let us know your bed type (liner, spray-in, or bare) and we can guide you or provide install tips. Some customers even weld them down for added theft protection.
