This cart is made for the messy job of a pan drop. It is a rolling cart that catches and holds seventeen plus gallons of fluid. There is a expanded metal screen to keep tools and parts from falling into the drained fluid. The screen is supported by two cross bars. To spread the load out more evenly we include a rectangular piece of plywood that sits on top of the screen. The bottom of the drain tank is equipped with a ball valve to make emptying the tank a snap. Tank Dimensions: 36" x 24" x 12"
