Hey there,

Thanks for posting! Your window operator is a match for either the 39-253RB or the 39-439B. To determine which of these is the correct replacement, you'll need to compare the attachment at the end of the arm and the specifications.

The compatible hardware and accessories can be found below their product descriptions on the website.
