The MILWAUKEE Caster Kit is designed exclusively for use with the PACKOUT Compact Debris Separator (49-90-2200). The kit includes (4) wheels that easily connect to the bottom of the Debris Separator, offering further maneuverability throughout the jobsite. The casters are a great add-on when using the PACKOUT Compact Debris Separator with other vacuums that do not offer PACKOUT capability or mounting clips. For stationary use, each caster individually locks in place. The casters offer enhanced durability to withstand jobsite environments.
