The Makita Dust Extracting Surface Grinding Shroud (195368-6) is designed to fit Makita 7 in. grinders. It features a spring-loaded suspension system that keeps the shroud flush to the surface during movement and compensates for blade wear. The shroud has a removable edge piece for surface work flush to edges or other objects. It also has soft brushes that help contain the dust and allow for smooth movement over the work surface. The outside diameter of the extraction port will work with most standard vacuum hose systems. The dust shroud is ideal for concrete finishing, concrete material removal, and paint or surface coating removal.
