How Much Weight Can A Craftsman Versastack System Hold?
The central benefit of any stacking portable toolbox system, such as the Craftsman Versastack, is that it can effectively lug most, if not all, of the assorted implements and accessories you need for either professional work or casual hobby crafting. Just stack all of those boxes and organizers on top of the rolling base, and you've got a little mobile tool station you can drag around the jobsite or load up onto a truck.
While lugging large quantities of heavy stuff is the Versastack's mission statement, that doesn't mean it has an infinite capacity. Even putting aside the fact that you can only fit so many tools and gadgets within the confines of a handful of toolboxes, there's also the concern of weight. It's important to know exactly what the Versastack's weight threshold is so you don't end up overstuffing it to the point that its wheels stop being functional and start being merely for appearances. The good news is that, if you've got the combined storage capacity of a rolling base and several toolboxes, you could haul up to 110 pounds of assorted equipment.
A Versastack stack can hold about 110 pounds
According to Craftsman's page for the Versastack Rolling Tower Storage system, which is made up of a rolling base, a deep toolbox, and a parts organizer on top, the total weight capacity depends on how much of the system you're actually using. If you're only using the rolling base on its own, you can carry up to 66 pounds of odds and ends. If you add the carrying capacity of the deep toolbox and parts organizer on top of that, then the entire stack's weight capacity increases to about 110 pounds.
Putting aside matters of physical space for a moment, that's enough weight capacity to carry a large quantity of Craftsman impact drivers or Craftsman drill/drivers, 44 and 23, respectively, plus 1.5Ah battery packs for the latter. If you're looking to start an on-the-go toolbox while shopping at a hardware retailer like Lowe's, the Versastack system should be able to safely accommodate a large amount of equipment, plus some assorted fasteners and components in the parts organizer, while still being able to safely roll around.
Incidentally, there are a few variants of the bundled Versastack system sold by Craftsman, such as one that swaps out the parts organizer for a small tool suitcase. While technically a different container, the page for this particular setup says that the maximum weight limit for all three containers is still 110 pounds. If you'd prefer to have something you can store power tools or hand tools in instead of a parts organizer, this configuration may be better for your needs.
