Thanks! I've been searching for this belt for a while - even the Riccar rep couldn't filnd a belt for this model.
Thanks Kevin. I think it's a model E340 or something like that. I measured my mother's vacuum belts, and both were 11" in circumference. I measured the broken belt from end to end.
The Flat belt is app 5 3/8" when flattened. The inner diameter of the round belt is app 3". But If you have your riccar model #, I can tell you the right belt.
