Help to identify parts

Thanks for your post! Your window operator could be either the 39-253RB or the 39-439B Encore Dual Arm Operator. You'll need to compare the differences between the two to determine which of them is the correct replacement. Take a look at the video tutorial below for a detailed explanation on the differences between them.

You'll find the opposite handed version of these operators as well as the compatible cover and handle kits tagged below this thread. The other compatible hardware and accessories will be found in the related items of the operator.
