Our 2-1/2" 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 red color indication ring allows for quick size identification of its 2-1/2” diameter. This Crevice Tool is compatible with MILWAUKEE® 2-1/2" Vacuum Hoses (49-90-2004, 49-90-2006) and other 2-1/2" diameter vacuum hoses.
