The set screw design made installation straightforward on my 48-inch drum fan motor shaft. It fits perfectly and the pulley spins true without any wobble, so my fan is running smoother than it has in months.

I was a bit nervous about getting the right size, but this pulley's set screw made installation on my 48-inch drum fan surprisingly straightforward. The 2.75-inch diameter matched perfectly, and now my fan runs quieter than it did with the old worn part.

Exactly the right size for my 48-inch drum fan—slipped onto the motor shaft and tightened down with the set screw in under five minutes. My fan is running smooth and quiet again, no wobble at all.
