The Milwaukee 48-22-8423 is an extra-large tool box in Milwaukee's PACKOUT modular storage line. It has an impact-resistant body, metal-reinforced corners and locking point, heavy-duty latches, an IP65 weather seal and a 100 lb capacity, plus an interior organizer tray. It stacks and locks with other PACKOUT components, so it works as the base or top of a rolling stack. It suits tradespeople who already own PACKOUT gear or want one rugged, weather-sealed box for bulky tools; rivals like DeWalt ToughSystem and Ridgid Pro Gear offer similar modular stacking, but PACKOUT has the widest range of add-on boxes, bags and mounting plates.

Owners of the PACKOUT line generally rate the XL tool box highly for its build and weather sealing, and treat it as a rugged stack component rather than a standalone box. Complaints center on its size and weight when full and on the effort needed to work the latches.
