Thanks for your post! You'll need either the 39-253RB or the 39-439B to replace your window operator. To narrow down the correct replacement match, you'll need to examine your operator to confirm which attachments it has. Take a look at the tutorial below for a detailed explanation on the differences between each operator.

The compatible hardware and accessories can be found on the website, in their related products.
