メナHi there, I’m Mena (@menachite), a hybrid engineer who handles both mechanical and electrical work.
The Milwaukee PACKOUT series is absolutely amazing, so I’m here to introduce it!
Its rival is the DeWalt ToughSystem series, but in terms of the sheer variety of products, the PACKOUT series takes the crown as a storage system.


The PACKOUT series is a large tool box series, so I think the storage capacity speaks for itself.
However, there are so many different types that it’s hard to get a full picture, which is why I decided to put this summary together.
This article is divided into three parts: tool boxes, tool bags, and wall-mounted storage.
This article covers tool boxes.



This time, we’re looking at the red beast made in America. Can it deliver three times the normal storage capacity?! Let’s put the PACKOUT series to the ultimate test!
Basic Specifications of the PACKOUT Series
First, let me explain the specifications that are common across the entire PACKOUT series.
Interlocking Mechanism Between Tool Boxes
One of the key features of the PACKOUT series is the slide lock system.
This is a system where tool boxes are connected by sliding one box on top of another.


To release the lock, you push the loop part shown above upward and slide it to release.
Since craftsmen often want front access when building cargo spaces, this design is beloved by professionals who work on vehicle cargo setups.
Dust and Water Resistance Rating: IP65
Think of this as protection against rain — it can handle rain but shouldn’t be over-relied upon.
Please be aware that you cannot expect more than this.
Like the DeWalt ToughSystem, this level of IP65 protection appears to be the standard for modular cases of this type.
Material: Polymer and Aluminum Frame
This also uses reinforced plastic polymer as the material.
Different brands have different variants in their polymer composition, but the differences aren’t particularly significant.
All four sides are reinforced with aluminum frames, which serve both as structural reinforcement and as design elements for customization.
Anti-Theft Lock Holes
Padlock compatible. This helps prevent tool theft.


Drawback When Stacking


One drawback when stacking is that the width becomes uneven as shown above.
Some users have noted this can be an issue when building vehicle cargo spaces, so please keep this in mind.
Obviously, when placing two smaller tool boxes side by side and connecting them, you need to ensure they are the same height before stacking another box on top — this is an important handling consideration.

Tool Bag Specs & Reviews
The tool bags in the PACKOUT series are characterized by their high durability, achieved through the use of thick 1680-denier nylon material.
Also, since they can be connected to PACKOUT™ modular system tool boxes, the bottoms are made of impact-resistant polymer.
In other words, these tool bags resist deformation and maintain their shape.
There is a lot to cover with the tool bags, so they are summarized in the following article.
How to Buy Milwaukee Products at a Great Price
Milwaukee tools and the PACKOUT series are high-performance products popular even among professionals, but they tend to be a bit pricey.
In that case, targeting Rakuten Ichiba sales events can give you a great opportunity to buy at a discount! Here are some key tips.
Take Advantage of Rakuten Super Sales and Shopping Marathons
Rakuten Ichiba holds large-scale sale events on a regular basis. During Rakuten Super Sales and Shopping Marathons, many products are sold at discounted prices, and there are bonus point rewards for shopping across multiple stores.
When sales typically happen: Usually at the beginning of the month and at seasonal transitions (March, June, September, December).
Tips for getting the most out of sales: Aim to purchase from 10 or more stores to earn up to 10x points — the trick is to combine your purchase with other items you need.
Check for Coupons and Flash Sales
During sale periods, Rakuten stores issue limited coupons and run limited-quantity flash sales. Tools and storage systems are often included in discounts, so it’s handy to add your desired items to your wishlist beforehand to receive notifications.
Our recommended store is Ehime Machine.
You can access them via the link above. They regularly run great sales, so be sure to check them out.
Summary
After going through everything, to give my honest take on the PACKOUT system: it’s simply massive, but it can do just about everything you’d want it to.
As expected, the range of accessories and options is extensive, making this a product suited for those who have a large warehouse, room, or factory of their own — and it’s firmly in the professional-use category, in Menatech’s view.
The downside is the cost — tool boxes range from around 10,000 to 30,000 yen.
Whether you can find value that justifies this cost is the key question when considering this tool box system.
Bring this red beast to any job site, and it’s sure to turn heads.
