The Milwaukee 48-22-8425 PACKOUT Large Tool Box is a modular jobsite storage box built for contractors, technicians, and serious DIY users who need durable tool storage that can travel. This is a tool storage box designed for organizing, protecting, and transporting tools and accessories on the jobsite. Model Number: 48-22-8425. If you are already using PACKOUT or plan to build a stack around one system, this box gives you larger enclosed storage with the durability Milwaukee is known for.

What makes this Milwaukee tool box matter is not just the size. It is the combination of 100 lb weight capacity, impact resistant polymer construction, and metal reinforcement in the spots that usually fail first. The corners are reinforced, the top handle is reinforced, and the locking point is reinforced. In plain terms, this box is built to deal with being loaded, carried, stacked, and knocked around in real work conditions without feeling flimsy.

The Milwaukee 48-22-8425 PACKOUT Large Tool Box is also built around day-to-day usability. An interior organizer tray helps separate smaller tools and accessories from the larger items stored underneath, so you are not digging through one big pile every time you need a driver, layout tool, or fastener box. Reinforced hinges and heavy-duty latches add to the overall feel of a box made for repeated opening and closing, not occasional garage use.

For outdoor work and messy sites, the IP65 rated weather seal is one of the most important features here. It helps keep out rain and jobsite debris, which is exactly what you want if the box lives in a van, trailer, truck bed, or unfinished building. It is not just about keeping the box clean. It is about protecting chargers, batteries, hand tools, measuring tools, and accessories from the kind of dust and moisture that shorten service life.

System fit is another reason this box stands out. It uses modular connectivity with all PACKOUT components, so it can lock into a larger rolling and stacking setup instead of becoming one more loose case to manage. There is also a mounting location for the ONE-KEY TICK, which is useful for users who want better asset tracking across trucks, crews, or jobsites. That is the kind of detail that matters more the more gear you own.

Size-wise, Milwaukee lists the exterior dimensions at 22.1 inches wide, 16.2 inches deep, and 11.1 inches high, with a product weight of about 12.2 lbs. That puts it in a useful middle ground: large enough for bulkier tools and mixed storage, but still manageable to carry on its own when needed. It is a good fit for cordless saws, hand tools, layout gear, and accessory kits that do not belong loose in the back seat or piled into an open tote.

Who should buy it? If you are in electrical, plumbing, HVAC, service work, remodeling, general construction, or mobile repair and you want enclosed storage that stacks securely with the rest of your PACKOUT setup, this is an easy yes. If you just need a cheap plastic box for occasional home use, it is probably more storage system than you need. But if your tools earn their keep and move with you, this PACKOUT large tool box makes sense because it protects gear, keeps it organized, and plays well with the rest of the Milwaukee storage platform.
