Extreme Tools EX Professional Series 33 in. 4-Drawer Deluxe Tool Cart (patent-pending) can be used as a stand-alone tool cart or it can be combined with the Extreme Portable Workstation. The most unique feature of this tool cart is the top storage compartment. Open the lid and you can access all your tools in the top drawer as well as tool hangers/holders on the sides of the cart. The closed lid securely holds a PVC coated MDF top creating a durable work surface and still allows access to the top drawer. It is the most versatile design you will find. Quick Release self-latching anodized aluminum drawer pulls keep drawers closed until you are ready to open them. Heavy-duty ball bearing slides on the drawers are load-rated 100 lbs. per drawer. The carts corners are covered in tough, impact-resistant non-marking bumpers. Four 6 in. x 2 in. proprietary Mag Wheel lockable swivel casters allow you to easily move the tool cart in your workspace. As an added bonus, we have included our Power Tool Rack accessory which hangs off the side of the tool cart and keeps your power tools within easy reach.
