Yes - It is a wall hanger for the power nozzle - The top of the sheeth snaps into it, and the hanger grabs onto it..
I don't use it since I still have the Eletrolux Storage Hanger I purchased when I got my mothers Marquis Back in 1987 - At the time it held the hose, power nozzle, combo floor tool, crevice tool, and aluminum wands...
With the new tools being different it only holds the hose, power nozzle, crevice tool, and bare floor brush, but will not hold the telescoping wand...
