Klein Tools 54808MB MODbox™ Tall Component Box, Half Width

Yes. The 54808MB tall half-width component box stacks top and bottom, so it interconnects with other MODbox pieces to build a mobile workstation. A one-handed release mechanism lets you pull it off the stack or reorder it without setting anything down. Its footprint is 15.5 inches wide by 10.9 inches long, and it stands 5.2 inches tall.

20 lb is the rated weight capacity, spread across 431 cubic inches (7.1 L) of total space. That is a parts-bin rating, not a tool-crate rating: wire nuts, connectors, terminals, fasteners and small devices are what it is meant to carry. The box itself weighs 4.9 lbs empty, which matters once you have several stacked on a cart.

It is weather resistant and IP65 rated, which means sealed against dust and against water jets, so rain and jobsite debris are covered. The shell is impact resistant polymer and the latch is heavy-duty metal rather than plastic. It is not a submersion rating, so do not treat it as waterproof if it ends up sitting in standing water.

No. The lid is a stay-put design that sits down onto the bins and keeps contents from migrating between compartments in transit, and the metal latch holds it shut. The lid is clear, so you can see what is in each bin without opening it, which is the difference between checking your stock at the truck and checking it after you have already walked to the panel.

No wheels on the 54808MB. It is a stackable component box, so it either gets carried or it rides on a rolling MODbox base underneath it. If you want a wheeled setup, plan on ordering a rolling MODbox unit as the bottom of the stack and using this half-width box above it.

Half width refers to the box occupying half the depth of a full MODbox footprint: 15.5 inches across the front by 10.9 inches deep. Two of them sit front to back in the space one full-width unit takes, which is how you split a stack between, say, device boxes on one side and connectors on the other. Only order what you have measured against your cart or truck shelf, since 15.5 inches is the width you have to clear.

No, and Klein says so directly: do not use it as a step stool or ladder. It is a 20 lb capacity component box, not rated for a person's weight, and standing on a stacked MODbox risks the release mechanism letting go under you. Use a proper step stool or platform ladder.

Order it as Klein Tools 54808MB. It comes in orange only, which is the standard MODbox color, so a stack built from mixed MODbox pieces reads as one system on the truck.
