The best stackable toolbox depends on what you carry, how far you move it, and how much exposure to dust or water it will face. Based on published manufacturer specifications—not independent comparative testing—Milwaukee PACKOUT is a strong fit when weather sealing and a rolling base matter, while CRAFTSMAN VERSASTACK offers tower configurations with defined rolling-unit and stack capacities. Choose a system around the exact boxes and loads you need; the evidence here does not establish cross-brand compatibility.
How to choose a stackable toolbox system
Start with the tools you carry and the way you reach them on the job. A rolling base can spare you from carrying a loaded stack, while trays, organizers, and drawers affect how quickly you can get to small parts or frequently used tools. Then check the published capacity and protection rating for each exact model—not just the product family name.
- Compatibility: Milwaukee describes PACKOUT components connecting within the PACKOUT system; CRAFTSMAN describes VERSASTACK units stacking within VERSASTACK. The cited manufacturer pages do not establish cross-brand interlocking.
- Exposure: The cited PACKOUT models carry a manufacturer-listed IP65 rating; the cited VERSASTACK towers are described as IP54-rated for dust and water resistance. Do not assume an unlisted model shares those ratings.
- Load: Capacity figures apply to specific boxes, rolling units, or configurations. Confirm the exact model and load context before choosing.
- Movement and access: Compare wheel design, handles, and how often you will need to lift or remove upper units to reach lower storage.
- Warranty and contents: Manufacturer pages list limited lifetime warranties for the cited products. Check current product documentation for terms and the components included in a tower.
Milwaukee PACKOUT: for a connected system with a weather-sealed rolling option
PACKOUT Tool Box, model 48-22-8424
Milwaukee lists this toolbox as compatible with PACKOUT modular storage products. Its published specifications include a 75 lb capacity, interior organizer trays, an IP65 weather-seal rating, and exterior dimensions of 22.1 × 16.2 × 6.5 inches. Milwaukee also lists a limited lifetime warranty. These are manufacturer specifications; the product page does not state their publication year. Milwaukee PACKOUT Tool Box
The shallow 6.5-inch exterior height and included trays make this model a candidate for organizing smaller tools or accessories separately from deeper storage. That is a practical fit assessment based on its dimensions and listed features, not a comparative access test.
#1 Best Overall
- Made of a heavy duty construction
- IP65 rated weather seal
- Interior organizer tray
- Dimensions: 22.1" x 11.3" x 16.1"
PACKOUT Rolling Tool Box, model 48-22-8426
For moving a connected stack, Milwaukee lists integrated locking cleats, 9-inch all-terrain wheels, an extension handle, an IP65 weather seal, a 250 lb capacity, and a limited lifetime warranty. Milwaukee’s page says the rolling toolbox connects with other PACKOUT system components. The 250 lb figure belongs to this exact model and should not be applied to other PACKOUT boxes. Milwaukee PACKOUT Rolling Tool Box
Consider this rolling model if the loaded stack needs to travel across a work area rather than be carried. The manufacturer identifies the wheels as all-terrain, but its page does not provide an independent mobility or durability comparison.
Rank #2
- Reinforced Safety: Locking safety bar for extra protection of your tools.
- High Capacity: Holds up to 50 pounds, ideal for storing heavy equipment.
- Internal Organization: Adjustable dividers for custom organization of tools.
- Smooth Slide: Drawers with metal ball rails for smooth opening and closing.
- Modular Connectivity: Complete integration with all components of the PACKAGE system.
CRAFTSMAN VERSASTACK: choose a tower configuration around the load
VERSASTACK CMST60402 tower
CRAFTSMAN describes this tower as a bottom mobile unit, middle deep toolbox, and top organizer. Its page lists the rolling unit at 66 lb and the stack at 110 lb, and describes IP54 dust and water resistance, connecting side latches, telescoping handles, and a limited lifetime warranty. Those capacity figures refer to different configurations and should not be treated as interchangeable. CRAFTSMAN VERSASTACK CMST60402
VERSASTACK CMST60406 tower
CRAFTSMAN presents this as three connected units: a rolling bottom unit, a middle toolbox, and a suitcase. The page describes IP54-rated material intended for dust and water resistance and lists a limited lifetime warranty. It gives both 66 lb and 110 lb capacity figures in different sections without making their load contexts clear in the cited information. Check the current product documentation for the exact configuration each figure applies to before relying on either number. CRAFTSMAN VERSASTACK CMST60406

Choose by jobsite routine, not by the number of boxes
- For a rolling PACKOUT stack: Start with model 48-22-8426 if the 250 lb manufacturer-listed capacity, 9-inch wheels, and extension handle match your needs; select each connected box by its own capacity and layout.
- For small parts and shallow storage: Consider PACKOUT model 48-22-8424 for its included organizer trays and listed dimensions.
- For a defined rolling tower: Compare VERSASTACK CMST60402’s stated 66 lb rolling-unit and 110 lb stack capacities with the actual load you plan to move.
- For a suitcase-style top unit: CMST17830 is described for cordless and corded tools and accessories and stacks within VERSASTACK.
- For another brand: DEWALT ToughSystem 2.0 and TSTAK are worth evaluating, but verify exact-model ratings and connections in DEWALT’s current documentation rather than assuming compatibility or borrowing figures from another model.
