Made from powder-coated high tensile steel, the Giantz Tool Chest and Trolley is built to keep your precious tools in their proper place with drawers that are specifically designed to cater to various tool sizes. It actually comprises two sections, a top 9-drawer tool chest with smaller drawers and a lower 7-drawer trolley with larger drawers. The 2-in-1 design allows the ensemble to be used individually or as a combined unit. From top to bottom, each drawer slides in and out effortlessly on quality ball bearings incorporated into the metal drawer runners. Every drawer is also lined to protect your tools and keep them from moving about. Plus, the tool drawers are installed with upgraded cam barrel locks that are more reliable and secured compared to general locks as well as hassle-free use. With the trolley, the top layer is also lined with an EVA pad for working convenience with frequently-used tools. The trolley is installed with omni-directional castor wheels (two with brakes) for easy 360 mobility and fast standing.
