If you’ve been looking at modular tool storage, you’ve probably already come across three names: DeWalt TSTAK, DeWalt ToughSystem 2.0, and Milwaukee PACKOUT. And if you’re anything like me, you’ve spent longer than you’d like trying to work out what the actual difference is between them and which one is worth your money.
So let’s clear that up straight away. TSTAK and ToughSystem 2.0 are both DeWalt products, but they are not the same system. They don’t use the same connection mechanism, and they’re aimed at different types of users. If you’re weighing up ToughSystem 2.0 against PACKOUT, I’ve covered that separately. This article is specifically about TSTAK vs PACKOUT, which is a different conversation entirely.
I’ve owned and used TSTAK for three years. My friend Andy, whom I work alongside regularly, has run a full PACKOUT setup through four years of daily site use. Between us, we’ve had plenty to argue about.
My overall take: TSTAK is a solid, affordable system for DIYers and light trade users. PACKOUT is the better long-term investment for anyone on the tools professionally every day. But the price gap is significant, and for a lot of people it won’t be justified.
Here’s one thing that might surprise you, though: those two DeWalt systems that can’t connect directly? There’s actually a fix for that, and it changes the conversation around DeWalt storage considerably. More on that below.
What is DeWalt TSTAK?
TSTAK is DeWalt’s lighter-duty modular storage system and has been around since roughly 2014. It’s the entry point into DeWalt’s storage ecosystem, widely stocked at Screwfix and Toolstation, and priced to appeal to DIYers and tradespeople who want organised storage without a big outlay.
The system uses a T-bar locking rail on the base of each box that clicks onto the lid of the box below. It’s a simple mechanism, the boxes are relatively lightweight, and the lids hinge fully open and stay out of the way. For day to day use, particularly when you’re grabbing individual boxes rather than moving a full stack, I think the TSTAK system is genuinely easy to work with.
So how does TSTAK compare to ToughSystem 2.0?
This is the question that causes the most confusion, and understandably so. Both are DeWalt, both are modular, both sit in the same aisle. But they are aimed at different users and built to different standards.
TSTAK is the lighter, more affordable option designed for workshop organisation and lighter van storage. ToughSystem 2.0 is DeWalt’s premium, heavy-duty system, IP65 rated with metal-reinforced corners, built to compete directly with Milwaukee PACKOUT on jobsite toughness.
The two systems have different footprints and completely different locking mechanisms, which means they cannot connect directly. However, they are not entirely incompatible. DeWalt produces an official adapter plate, the DWST08017-1 ToughSystem 2.0 to TSTAK Adapter Plate, available at Screwfix, which allows you to stack a TSTAK box on top of a ToughSystem 2.0 unit. It’s not a seamless solution, and you’ll need to factor in the additional cost, but it does mean a mixed DeWalt setup is possible if you’re transitioning between systems or want to combine elements of both.
If you’re starting from scratch though, my honest advice is to pick one system and stick with it. Mixing them adds cost and complication, and neither setup will feel as cohesive as committing to one from the start.
What is Milwaukee PACKOUT?
PACKOUT is Milwaukee’s premium system, and the one every serious tradesperson seems to end up on eventually. Thicker walls, metal corner reinforcement, and a cleat-based stacking system that locks solid. A loaded PACKOUT stack doesn’t wobble.
A colleague of mine has run the same PACKOUT setup through four years of daily site use. Nothing broken. That kind of longevity justifies the price if you’re working hard with it.
The ecosystem is also massive, over 50 compatible components, giving you room to build a serious mobile setup over time. TSTAK hits its ceiling much faster.
The trade-offs: 25 to 30 per cent more expensive per piece, heavier individual boxes, and that loud red colour that advertises your van contents to anyone walking past.
TSTAK vs PACKOUT: At a Glance
| DeWalt TSTAK | Milwaukee PACKOUT | |
|---|---|---|

| Stacking Stability | Wobbles under load, less confidence moving a full stack | Rock solid, cleat system locks tight |
| Ease of Access | Excellent, lids open fully, light to carry | Good, but heavier individual boxes |
| Ecosystem Size | Limited, around 20 components | Huge, 50+ components |
| UK Price (trolley set) | ~£120 to £150 | ~£298 |
| Best For | DIY, light trade, budget builds | Daily tradespeople, van-based setups |
Build Quality and Durability
After three years of ownership, I feel the TSTAK system is adequate for what it is, but it has limits. I dropped one of my TSTAK boxes off the back of the van onto a concrete driveway, not a massive drop, maybe two feet, and it cracked. That’s not what you want from a storage system you’re relying on. The plastic feels noticeably thinner than PACKOUT and the hinges, while functional, don’t inspire the same confidence.
I’d agree the PACKOUT is a premium product when it comes to build quality. Andy has been running his setup through daily site use for four years and hasn’t had a single latch failure or cracked corner. The walls are thicker, the corners are metal reinforced, and the whole thing just feels like it was built to take abuse. You can feel the difference the moment you pick one up in a store.
If your storage is going in and out of a van every day, getting stacked on rough ground, and taking the occasional knock, PACKOUT is the more honest long-term investment.
Ease of Access and Usability
This is where I think the TSTAK system genuinely holds its own. The lids hinge right back and stay open, the boxes are lighter to carry individually, and the overall design feels less cumbersome when you’re just grabbing what you need quickly. After years of using mine, I find it less fatiguing to work with on a day to day basis, particularly when I’m moving single boxes rather than a full stack.
Andy’s view on this was interesting. He admitted PACKOUT boxes are heavier and that moving individual ones around gets tiring. His workaround is to keep his stack on the trolley and roll it rather than carry individual pieces, which works well for his van setup but wouldn’t suit everyone.
If ease of access and lighter handling matter to you, TSTAK has a genuine advantage here.
Stacking Stability
This is one of the areas where I feel the TSTAK system lets itself down most noticeably. A tall stack of loaded TSTAK boxes wobbles more than I’m comfortable with when moving it around a tight site. The T-bar connection does the job, but it doesn’t inspire confidence when you’re rolling four or five boxes across uneven ground.
I dropped a stack once, not entirely the system’s fault, but the wobble didn’t help. The boxes that cracked were the ones that hit hardest.
PACKOUT’s cleat system is a different experience entirely. My discussion with Andy on this was an interesting one, because he’d actually come from a TSTAK background before switching. His words: “Once you’ve moved a loaded PACKOUT stack across a site, you won’t go back. It just doesn’t move around like TSTAK does.” I think that’s a fair summary based on what I’ve seen firsthand.
Modularity and Accessories
The biggest advantage I found with the TSTAK system is the range of storage options. While the overall ecosystem isn’t as extensive as PACKOUT, I actually prefer the selection of boxes, organisers and drawer units that DeWalt offers. The drawers are particularly useful because you can access your tools without having to unstack the whole system, and I find the cases generally easier to carry, rearrange and work from on site.
PACKOUT still has the larger ecosystem overall, with more than 50 compatible components including vacuums, radios, tool bags, wall storage and purpose-built inserts for specific Milwaukee tools. If you’re heavily invested in Milwaukee and want to build a fully integrated mobile workshop, it’s hard to argue against the flexibility PACKOUT offers. Andy has been expanding his system over the last four years and still hasn’t reached its limits.
For me though, I don’t need dozens of specialised accessories. I prefer the practicality of the TSTAK boxes and drawers, and I find the system quicker and more convenient to access during day-to-day jobs. While PACKOUT wins on the size of its ecosystem, I actually prefer the way TSTAK stores and organises my tools.
Price
This is where TSTAK makes its strongest argument. A typical TSTAK trolley set will cost somewhere in the region of £120 to £150, compared to around £298 for a comparable PACKOUT set. That’s a significant difference, and it compounds as you add more pieces.
| DeWalt TSTAK | Milwaukee PACKOUT | |
|---|---|---|
| Trolley set (approx.) | £120 to £150 | ~£298 |
| Individual box (approx.) | £25 to £40 | £55 to £80 |
| Where to buy | Screwfix, Toolstation, Amazon | Screwfix, Toolstation, Amazon |
When Andy and I talked through the cost difference, his view was straightforward: “If you’re using it professionally every day, the PACKOUT pays for itself in longevity. If you’re not, the TSTAK is fine.” I think that’s the most honest framing I’ve heard.
Worth noting: both systems go on promotion regularly at Screwfix and Toolstation, so it’s worth checking before you buy.
Which Should You Buy?
Buy TSTAK if you’re a DIYer, weekend warrior, or light trade user who needs organised storage without spending big. It’s easy to use, widely available, and perfectly adequate if it’s not getting thrown around daily. Just don’t expect it to take the same abuse as PACKOUT.
Buy PACKOUT if you’re on the tools every day, loading and unloading a van regularly, and need storage that genuinely keeps up. If you’re already deep into Milwaukee tools, it’s a no-brainer. If you’re a DeWalt user torn between brands more broadly, my DeWalt vs Makita comparison might be worth a read before you commit to a storage system that locks you in long term.
Still unsure? If you already own DeWalt tools and want storage that integrates with a workshop or van racking setup, also consider ToughSystem 2.0 before committing to either. It sits between TSTAK and PACKOUT on price, and for many tradespeople it’s the sweet spot. I’ve covered that in detail in my Milwaukee PACKOUT vs DeWalt ToughSystem 2.0 comparison.
FAQ
Is DeWalt TSTAK compatible with Milwaukee PACKOUT?
No. Completely different connection systems, they won’t stack together.
Is DeWalt TSTAK compatible with ToughSystem 2.0?
No, and this catches a lot of people out. Both are DeWalt products but they use different stacking mechanisms and are not cross-compatible. Mixing the two means boxes that won’t connect.
Is PACKOUT worth the extra cost?
For daily professional use, yes. For occasional DIY use, probably not. TSTAK does the job at significantly lower cost if you’re not working it hard every day.
Does DeWalt make a PACKOUT equivalent?
ToughSystem 2.0 is the closest match, built to a similar professional standard.
