The racket fits like a glove! This is a good product. Durability is not known as it has just been installed. However, the brush does not get along with the husky under the fur! The inclusion of 6 straps is very important. In case you're interested, I have an Oreck XL2 Ultra model 3910H2B. If you've never taken your Oreck apart before, I recommend giving the motor a thorough cleaning with another vacuum or brush. Also note that there is a flat guide at the end of the motor shaft to prevent the belt from coming off the shaft. When removing the old belt and installing the new belt, be careful not to damage the guide. The replacement belt must first be mounted on the motor shaft.
