Hope this picture helps. A great way to determine the handle is to identify the operator. Look on the operator itself to see if there is a name on it. A good place to check is the operator arm. To do this, remove the window screen & crank open the window. You should see a name on the long operator arm. Also, do you have a Wood, Vinyl or Aluminum window? Wood & vinyl windows usually have a 11/32" spline similar to our 39-102 (but not all the time). Aluminum or metal windows usually have a 5/16" or a 3/8", similar to our 39-108 .
