From the Manufacturer
The Little Giant Fuel Tank vertical ladder roller tray holds a full gallon of paint or other fluids. Just fill the Fuel Tank to the right level, dip your roller in the paint, run it over the molded ridges, and paint. The Fuel Tank allows you to work with significantly more paint, so the days of continuous filling and spilling with your traditional paint roller tray are in the past. A handy magnetized paint roller and brush holder keeps your tools out of your paint, and your paint off of your floor. And cleanup is a breeze. When you're done painting, just let the paint dry over night and in the morning it'll peel clean away leaving your Fuel Tank looking like new. You can also use the Fuel Tank for window washing and other cleaning projects.
