Extreme Tools TX Series TX362505RBBK Deluxe 36-in Reinforced 5 Drawer Extra Capacity Road Box is a tough, sturdy tool box. Our engineers designed it to withstand the rigors of transport as well as the jobsite. The five heavy-duty drawers use friction slides which are meant to endure on road travel. Each drawer can hold up to 150 lbs. The specially formed handles make it easy to move and provide a protective frame. The lid covers the drawers in the closed position and locks to hold the drawers in place during transport. We left space underneath so that a forklift can easily move a fully loaded road box wherever you need it. We also made it caster-ready, so you can add optional casters to make moving it even easier (casters sold separately.) We took extra care in designing features to make this box as theft resistant as possible. This deluxe road box also has weather-resistant features like drip troughs on both sides that channel water away so it will not get inside and a wrinkle finish that resists scratches and the weather. It is everything you could want in a road box!
