This ProTeam overhead pipe cleaning attachments are perfect tools for vacuuming and dusting hard to clean overhead ducting and pipes. When paired with any 1½ inch wand and wand extensions, you can eliminate the use of ladders and avoid any chance of falls associated with the use of them. Time is also saved thanks to not having to climb up and down the ladders as well as having to reposition them every few feet. These attachments have a specialized curved surface that wraps around any rounded surface, effectively cleaning the area better than any straight tool could accomplish. This tool comes in two different sizes. The smaller size works better to clean pipes that are 1 - 4 inches in diameter. The larger sized tool is more geared for 4 - 8 inch ducting and pipes. If you need a tool kit that includes extensions to use with these attachments, please take a look at our ProTeam High Dusting Tool Kit which will give you all the equipment to allow your vacuum to reach to high up areas. This kit and these attachments work well with backpack vacuums to allow you the maneuverability to effectively and quickly clean your work area.
