Adapter for 3-prong Cords - NO LONGER AVAILABLE
Adapter fits on 3-pin power brush cords (that are not manufactured any longer) and fits into a new 2-pin-hole hose such as the Electric Hoses that start with the numbers 351, 352, 353.
Instead of using this product, a better way to resolve the issue is to use these two parts 406SU and 480AC
together. This is a new upper wand section and short adapter cord that plugs into two of the three prongs (the third prong is a dummy prong), and then has two pins that plug into the new hose.
