Timer Knob was broken & impossible to turn the timer without using a wrench

Part arrived earlier than expected & when replacing the knob I merely lined it up with the timer shaft which was a 1/2 round shaft. It slipped on very easy & I just pushed the knob on as far as it would go. Replacement of the knob makes life much easier in being able to turn the timer on without use of a wrench. Very, very satisified customer.
