Milwaukee Packout Toolbox Attachments: 8 New Ways to Expand Your Stack

Introduction

The Packout system has long been one of the most complete modular tool storage platforms available, and Milwaukee is now pushing it further. The company has announced eight new Packout toolbox attachments designed to lock securely onto the metal reinforced corners of an existing stack. The idea is simple: instead of digging through boxes for the things you reach for constantly, like batteries, hand tools, and small parts, you mount them on the outside of the stack and turn it into a more mobile workstation.

The official messaging explains the problem being solved. Professionals in the field regularly need to transport larger tools such as levels, conduit, and other long handled solutions that simply do not fit inside a toolbox. These attachments store those items on the outside of the stack. Launch dates vary by attachment, and no pricing has been announced yet, but here is what each one offers.

Quick Battery Access: M18 and M12 Battery Racks

Two of the new attachments target the most commonly swapped item on any job site: batteries. The Packout M18 battery rack attachment and the Packout M12 battery rack attachment provide quick battery access and clip in battery storage, hanging on the outside of the box so charged batteries are ready to grab without opening a lid or rummaging through drawers.

The design is deliberately plain and simple. There is no charging function here, and for many users that is fine: if your batteries are already charged for the day, you clip them in and go. It removes the daily hunt for batteries that end up scattered in drawers or moving between boxes. The racks mount onto the metal rails of the stack, finally putting those long-existing rails to practical use. They are separate units, so you choose the platform that matches your battery fleet.

Three Hook Attachment

The Packout three hook attachment offers a 30 lb weight capacity and is designed to store and quickly access power tools and more. The adjustable three position hooks save space by allowing them to be adjusted to the left or to the right when not in use, so they do not snag or add bulk when the stack is packed up.

Placement matters with this one. Depending on how tall your stack is, you may only fit one hook attachment per side, mounted higher up so hanging tools clear the boxes below. Used left and right, it effectively adds a hanging zone for things like a flashlight or smaller tools you want within arm’s reach.

Long Tool Holder Attachment

The Packout long tool holder attachment consists of an upper and lower toolbox attachment that lock directly into the metal reinforced corners of the stack. Its purpose is straightforward: carrying levels, conduit, and other longer handled tools that have never fit inside standard boxes.

Compared to similar solutions on competing modular systems, this one looks a little beefier, which matters when you are lashing long levels to a rolling stack and moving it across rough ground. For trades like drywall, electrical, and framing, this may be the most practical piece of the entire announcement.

Toolbox Caddy Attachment

The Packout toolbox caddy attachment stores hand tools, accessories, and more. Adjustable dividers allow further customization, so you can lay it out for whatever mix of items you carry, from hand tools to smaller accessories. When not in use, it stores on the back of the attachment with onboard storage, keeping the stack profile tidy.

This is the kind of open organizer that suits fast-moving work where you want to see and grab what you need rather than open latched compartments. Think screws, blades, markers, and other small consumables that get lost inside bigger boxes.

Belt Clip Rack

The Packout belt clip rack provides another level of storage specifically for belt clip tools. It is metal reinforced and maintains its shape when fully loaded, which addresses the usual weakness of soft-sided holders sagging under weight.

If you already run belt clip tools on the site, this gives them a defined home on the side of the stack instead of loose in a drawer. It is a niche addition, but a sensible one for anyone whose most-used tools are always clipped to a belt.

Toolbox Tray and Compact Plate

The Packout toolbox tray attachment stores bins, bit cases, and more to give fast access to the parts and materials commonly used on site. It is built with an impact resistant body for durability under tough professional job site conditions.

The Packout toolbox compact plate is the most flexible of the group: it lets you store organizers, hooks, racks, holders, and more on the side of the stack. The side mount has a 30 lb weight capacity, letting professionals carry more while keeping quick access storage. Like the other attachments, accessories mounted to it lock securely onto the metal reinforced corners.

Buying Advice

The strongest picks depend on your trade. If you run a Milwaukee battery fleet, the M18 and M12 battery racks solve an everyday annoyance with an elegant clip-in design. Carpenters and drywall crews will lean toward the long tool holder for levels and long handled tools, while the three hook attachment and caddy suit anyone who wants small tools and consumables visible and reachable. The compact plate is the best starting point if you want maximum flexibility, since it accepts a range of organizers and holders.

Two things to keep in mind: launch dates vary across the lineup, and pricing has not been announced, so check availability before planning a full setup. Also note that these attachments are designed for the Packout system’s metal reinforced corners, so they make sense primarily if you are already committed to that platform.

Conclusion

This wave of eight attachments makes the Packout stack considerably more versatile, moving frequently used batteries, hand tools, and oversized items to the outside of the stack where they are easier to reach. Nothing here reinvents tool storage, but together the pieces turn a rolling box into something closer to a mobile workstation. If Packout is already part of your workflow, several of these are likely to earn their place quickly.
