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.
