Just what i needed
I needed a very small belt for my rock polisher, and it was just the right size.

My mistake? fixed!
I needed a 3L330 V-Belt and somehow I think either I typed 5L330 although I was using an online conversion chart to match up belt numbers which might have had a typo there. The delivery is always good from MRO. I contacted MRO by email late that night after work with my silly situation and then rather than wait for a reply I ordered the right belt number so I could get the job done. I got a reply the next morning with instructions for the return procedure then the very next day I had the right belt delivered. Then I received another two contacts from the returns agent and customer support agent both telling me not to return the wrong belt and I would be refunded the purchase amount. Outstanding helpful support and the 'fastest delivery in the west'. MRO people are the best all around. Great products and extensive choices. I am retired now after 50 years in manufacturing equipment operations and maintenance with Nashua then Kellogg's but still I love working on machines and fixing things. MRO is a great source for many things even as small as a lawn & garden V-Belt they take care of the little guy too. Great people at MRO Supply.
