This is a factory replacement belt for a Bosch Midsize Power Brush that is available on the Formula and Premiere Series Canisters. It is the belt for the PB417.
Here is a hint:
Buy two and store the second belt in the bottom of your vacuum for future needs! When the belt breaks once again you will never need to search for a new belt or wait for a replacement to be shipped to you.
SAVES ON SHIPPING COST TOO!
