Dustie 7" Dust Shroud (D1854) by Dustless. The Dustie is an economic, DIY solution to dust storms created when grinding concrete. A universal mount allows it to attach to nearly any 4"-5" grinder. This shroud is meant to be one-time-use, so once you have completed grinding the main section, you can cut the shroud for grinding close to walls. This will allow you to grind more flush to walls and corners while still containing the dust. The Dustie works best and complies with EPA laws and OSHA guilelines when used with a certified HEPA vacuum system of 175 CFM or higher. The Dustie will fit directly to any 1.25" hard hose end.
