This belt fits the Dyson DC17 models, all variants.
*Note - this is the new style belt for the Dyson DC17. It is wider than the older style belt. The skinny, older style belt is no longer in production. If your vacuum has the older style (skinny) belt, you will need to replace some other parts, such as the brushbar assembly.
