We use these belts for oilfield applications. They last very well in hot harsh conditions. We have expanded our use to other customers in the area who are very satisfied with the price and quality of these belts.

I sold it in my store.

I modified a tractor deck mower to run 2 belts instead of 1 so I wouldn't go through a belt a month. So far, it's worked great. Belts are affordable, solid quality, and sold by size which is exactly what you need when you start making your own design mods.
