[Quality Material]:Who doesn't love a product that is built to last? Made of high-strength polypropylene with easy-to-maintain clean surfaces and rust, water and corrosion resistance, the carts are sturdy and warp-free. The upper and lower trays have a weight capacity of up to 550 pounds, making them suitable for long term, intense work use.

[Lockable Universal Wheel]:The tool trolley contains 4 universal wheels, two of which have locking systems. It's easy to maneuver even in tight workspaces, and the locking casters help keep the cart in place when you're stationary. The rollers made of PVC can provide you with a quiet working environment and protect your floor from scratches.
