This tool kit is a great addition to any garage. To be used with either a standard 1 1/4" hose that would be included in all VacuMaid Garage Vacs. The black cuff will thread onto the end of the 1 1/4 hose and the other side will fit the tools. Must remove the curved wand from the end of the hose to be able to thread the black cuff onto the hose.
