The Roll A Bucket is a 6 gallon bucket. It is recommended to hold up to 1.75 gallons at a time to allow access paint to come off of the paint grid. The paint grid is designed only to fit this bucket. Designed with a secure rest to hold a 9" roller that can easily be used to push the bucket around. Features a spout and underneath grip to allow easy pouring of leftover paint back into the can. The three inch, alloy caster wheels allow easy maneuverability over carpeting, drop cloths and other surfaces. Bucket comes with one grid. Additional grids can be purchased separately.
