The Milwaukee Air-Tip Bucket Topper Dust Collector delivers secure bucket attachment for dust plume containment. The Bucket Topper clips onto the top of a 5-gallon bucket to help contain dust plumes during pouring and mixing applications. This results in less dust exposure in the environment, making the jobsite safer and cleaner. With a crescent-shaped design, users have the ability to mix effectively while the Bucket Topper is installed. The Milwaukee Air-Tip Bucket Topper Dust Collector is compatible with other wet/dry vacuum brands with 1-1/4 in. , 1-7/8 in. , and 2-1/2 in. diameters, and is part of the Air-Tip family of Vacuum Accessories.
