I have a Kenmore vacuum (no canister) and it says Belt: CB-3. Even though it's a CB-3 belt, it doesn't fit. This strap is about half the length needed for a Kenmore stand. It is not clear why Kenmore chose to label different straps with the same designation. So if you have a Kenmore body, even if it says CB-3, it's not the right belt. I'm sure it's a fine belt when set to the correct vacuum.
