The Makita T-90021 MAKTRAK Extra Large Extension Tool Box is a modular jobsite storage box built for transporting, storing, and organizing larger tools and equipment. This is a tool box designed for jobsite tool storage and transport. Model Number: T-90021. If you need one box in the MAKTRAK system that handles oversized gear without wasting space, this is the one aimed at that job.

What separates it from a basic plastic box is usable capacity. Makita rates it at 3,569 cubic inches with a 100 lb capacity, so it is built for bigger cordless tools, larger accessories, and awkward items that do not sit well in smaller organizers. That deep box design is the whole point here. Instead of forcing large tools into shallow compartments, this box gives them the vertical room they need.

The lid setup is another practical upgrade. The dual-hinged removable lid allows access from both sides, which is a real advantage when the box is loaded in a truck, stacked in a modular setup, or positioned against a wall on site. You are not stuck approaching it from one direction. Makita also added multiple lid mounting points for extra interior organization, which gives users more ways to set up the inside around the tools they actually carry.

For daily handling, the details make sense. Large glove-friendly latches are easier to work with when your hands are dirty or gloved up, and the comfort-grip carrying handles matter when the box is loaded anywhere near its limit. The body is made from impact-resistant copolymer, so it is intended for rough transport, repeated loading, and jobsite conditions that would quickly show up the weak points in a light-duty box.

This storage solution also supports the broader MAKTRAK modular storage platform. The box can horizontally cleat mount or vertically connect to the Rolling Tool Chest, so it is not just a standalone box. It is part of a stackable transport and organization system. The included storage tray is designed with space for batteries and a charger, giving it a practical role for cordless tool users who want to keep charging gear together inside the box. Charger and batteries are sold separately.

The Makita T-90021 MAKTRAK Extra Large Extension Tool Box makes the most sense for contractors, service techs, remodelers, electricians, plumbers, and serious DIY users who carry larger tools and want a cleaner way to move them between the shop, truck, and job. If your current storage setup is a pile of mixed cases that wastes space and slows you down, this box is the kind of upgrade that solves a real problem.
