I have a great Shark cordless vacuum cleaner. I still have a lot of old nozzles from previous vacuum cleaners. The shark is 1 3/8" and all my old baits are 1 1/4". This inexpensive adapter works great and allows me to use all the old attachments I've accumulated over the years. Now you don't have to buy expensive nozzles.
