Our 1-7/8 in crevice tool is designed to access tight areas and makes cleaning around edges easier. The vacuum crevice tool allows you to clean hard-to-reach areas where other vacuum attachments will not fit. The gray color indication ring allows for quick size identification of its 1-7/8 in Dia. This crevice tool is compatible with MILWAUKEE® 1-7/8 in vacuum hoses (49-90-1996, 49-90-1984, 49-90-1986) and other 1-7/8 in Dia vacuum hoses.
