Tool Storage
ToughBuilt Stack Review: A New Modular Tool Storage System That Undercuts the Big Names
Hands-on with the ToughBuilt Stack, a rugged IP65-rated modular tool storage system launching at Lowe's with aggressive bundle pricing and a deep accessory roadmap.
Introduction
The ToughBuilt Stack is a new modular tool storage system launching at Lowe’s, and after spending hands-on time with the full launch lineup, it is clear this is not a half-hearted entry into the market. The system arrives with eight core boxes, a metal rail interlocking design, an IP65 rating, and a roadmap of drawers, coolers, first aid kits, and job-site accessories that rivals anything from the established players.
The launch lineup covers nearly every storage need: a tool bag, a compact organizer, an ammo-can style lockable box, a large organizer, a briefcase-style tool box, a tool crate, a large tool box, and the rolling tool box that anchors the whole system.
First Impressions: Build Quality and Design
Out of the box, the system feels genuinely rugged. Every full-size box carries accessory rails on all four corners, and even the half-size boxes keep the rail on both sides, which is not something every competitor bothers with. The rails are metal, removable with a security Torx bit, and bolted down with visible screw points. The front of each box gets a metal lip that protects against slams and keeps the box rigid over years of use.

The rolling box serves as the base of the system. Its telescopic handle extends with one hand, combines metal and plastic construction, and can be removed entirely with two flips of a switch, which is a genuinely useful detail if you store your stack under a tonneau cover. The rubber wheels use a honeycomb design with no air, spin with low resistance, and wear aggressive treads. Side handles let you grab and drag the entire stack sideways, which is one of those small touches you end up using constantly in a shop.
The tool crate deserves a special mention: unlike most systems where a crate has to sit on top of a stack, this one has mounting points on its own lid, so you can lock other boxes directly on top of it.
Latches, Locking, and Weather Protection
The latch system is the headline feature. Each connection uses a three-position indicator: unlocked, ready to lock, and locked. The yellow lever is only an activator; the actual connection happens at wide front and rear latch points. At a glance you can tell whether the stack is secured, and the wide latches feel substantial enough that twisting or breaking them by hand seems unlikely.

Every box carries a lock point for a padlock, and the rolling box lid seals with a rubber gasket that contributes to the system’s IP65 rating. In practical terms, that means complete dust protection and resistance against rain and driving storms. It is not submersible, so do not take a pressure washer to it, but leaving it out in a serious downpour is not a concern.
Inside the Boxes: Trays, Dividers, and Organizers
The rolling box is deep, with a lid that locks fully open without struts, and it includes a solid tray that sits in recessed points so it will not slide around. The large tool box is a slightly smaller version of the same design, and its tray is dimensionally identical, so trays stack on top of each other if you want to carry two.
The briefcase-style box is the everyday carry of the lineup, with two layers of removable dividers and partitioned compartments. The organizer box adds a clear lid so you can see contents at a glance, along with large solid bins that stack on themselves and removable divider plates.

The ammo-can style lockable box is a standout for anyone who wants a small, tough, lockable metal-latched container with the same gasket and tray system. One quirk worth knowing: once you stack a box on top of another, you generally cannot open the lower box without unlatching it first, so plan your stack order around what you need to access.
What Is Coming Next
The launch is staggered. A spring and summer release follows the initial rollout, and the roadmap is where the system gets genuinely exciting. Drawer boxes are confirmed, including a rolling box with one giant full-width bottom drawer, single-drawer suitcase and large boxes, and double, triple, and even four-drawer configurations. A lack of drawers at launch is the main reason the system earns a B+ rather than an A today, but the drawer lineup coming next year addresses that directly.
Beyond drawers, the roadmap includes an XL box the same size as the rolling box but without wheels, a full-width ultra-slim compartment box, a half-size ammo can and clear-top version, a half-size milk crate, an integrated ice pack and cooler system, first aid kits, a water box with a tap, and a vacuum system. There is also a full bag system that locks into the rails, work lights including an articulated drafting light, a magnifying ring light, a paper towel holder, MOLLE straps, a wood work surface, and a quad-pod work light.
The mobility accessories may be the most ambitious part: a convertible dolly-cart system for finished floors, a height-adjustable levered transport system claimed to let one person pull 500 pounds of equipment out of a truck bed, and a two-point receiver hitch mount that turns any vehicle into a four-point mobile work station. A full workshop ecosystem of ToughBuilt cabinets, shelving, and workbenches is also planned.
Price and Value Compared to Packout, TSTAK, Flex, and Klein
The system launches at Lowe’s with a buy-more-save-more promotion. The standard tower, combining the rolling box, large box, and briefcase-style box at list prices of $125, $80, and $65, drops $70 to $199 on sale. Other launch pricing includes the large organizer at $60, the small parts organizer at $28, the ammo-can box at $65, the milk crate at $50, and the tool bag at $90.
Stacked against the competition, the comparison is favorable. The equivalent Milwaukee Packout configuration runs about $309 non-sale, and the classic Packout bottom box has not been seen at its old $200 sale price in years. The ToughBuilt tower sits slightly above DeWalt TSTAK pricing, below Flex’s roughly $300 basic system, and well under Klein ModBox, whose limited system breadth makes comparison difficult at its $320 entry point.

For a professional-grade system arriving at or below the price of most established competitors, the value proposition is strong, especially given how complete the accessory roadmap already looks on paper.
Buying Advice
Buy the standard tower on launch promotion if you want a full base system, since the $199 bundle pricing is the best deal in the lineup. Add the organizer and small parts organizer if you handle fasteners and small hardware, and the ammo-can box if you need a lockable, weatherproof container. If drawers are essential to how you work, it may be worth waiting for the spring release, though the current system is complete enough on its own for most trades.
Conclusion
The ToughBuilt Stack is an impressively thought-out entry into modular tool storage: metal rails on every box, a genuinely good three-position latch, an IP65 rating, a removable truck-friendly handle, and a roadmap of drawers and accessories that few competitors can match. It launches at or below the price of the major professional systems, and if the company keeps delivering on its stated release schedule, this is a system worth investing in now rather than later.
