The Milwaukee PACKOUT Tool Box Caddy Attachment, model 48-22-8602, is a modular exterior storage add-on for PACKOUT tool boxes. This is a tool box caddy attachment designed for quick-access hand tool and accessory storage on the jobsite. If you already run a PACKOUT stack and want screwdrivers, pliers, markers, tape measures, knives, and small gear where you can reach them fast, this attachment solves that problem without taking up space inside the box.

What matters most here is access. Instead of opening a lid every time you need a driver, layout tool, or clipped accessory, the caddy keeps frequently used items mounted on the outside of the stack. That saves time on punch lists, service calls, remodel work, and any job where you're moving around constantly and grabbing the same few tools over and over.

The layout is built around practical storage, not just extra capacity. Milwaukee uses a reinforced belt clip rack so clipped items like tape measures and knives have a more secure place to ride. Adjustable dividers let you organize the main compartment for different tool mixes, and those dividers can be removed and stored on the back of the attachment when you do not need them. That is a smart touch because it gives you flexibility without leaving loose parts rolling around in the truck.

The body is made from polypropylene and built with an impact-resistant design, which matters for something hanging off the side of a mobile storage stack. This is not a delicate organizer tray. It is meant for daily use around other boxes, carts, van shelves, and jobsite debris where bumps and knocks are normal.

Compatibility is the real buying decision with this product. The Milwaukee PACKOUT Tool Box Caddy Attachment is made to lock onto PACKOUT tool boxes with metal-reinforced corners using the included attachment mounts. It is part of the PACKOUT modular storage system, so it makes the most sense for users who already own compatible PACKOUT boxes and want to customize them instead of replacing them.

At 16.8 inches long, 6 inches high, 5.5 inches wide, and 1.93 pounds, it adds useful storage without being a huge bulky add-on. That size works well for commonly used hand tools and everyday accessories while still keeping the overall stack manageable. For contractors who like a place for the tools they reach for first, this caddy is a lot more useful than it looks in a spec sheet.

This storage accessory is a strong fit for electricians, HVAC techs, service plumbers, maintenance crews, remodelers, and general contractors who run mobile setups and want faster organization. If you are already invested in PACKOUT and you want better exterior storage instead of digging through boxes, this is the kind of attachment that makes your stack work harder.
